What is Steel? Applications of Steel in Our Life

Steel is a crucial industry for economic and social development. Not only is steel highly applicable and pervasive in daily life, but it is also a valuable resource symbolizing technological and scientific advancement in nations, especially developing ones. The development of the steel industry drives the industrialization of a country, thereby addressing employment needs for a significant labor force and supporting the growth of related industries. However, not everyone understands this industry well. MaTec Vietnam will provide you with important information about steel and the steel industry to help you better understand this key sector and its impact on the mechanical processing industry. What is Steel? Steel is an alloy primarily composed of iron (Fe), melted with carbon (C) and several other chemical elements (Si, Mn, P, S, Cr, Ni, Mo, Mg, Cu, etc.). The chemical elements in the steel alloy and their concentrations play a role in adjusting the hardness, elasticity, ductility, oxidation resistance, and strength of the steel. Due to this diversity, there are over 3,000 types of steel worldwide.   Chemical Properties of Steel Steel is a metallic material, so it has a metallic luster, and is highly conductive of electricity and heat. At temperatures between 500°C and 600°C, steel becomes ductile and its strength decreases. At -10°C, its ductility decreases. At -45°C, steel becomes brittle and prone to cracking. Steel possesses high overall mechanical properties, good formability, and comes in many types with various uses, making it a highly versatile material. It is widely used in industries such as construction, mechanical manufacturing, and shipbuilding. Properties Of Steel In the steelmaking process, varying the ratio of carbon to iron can create a wide range of steel structures with different properties. Thus, steelmaking does not produce a single uniform product; the type of steel produced depends on the needs and intended use. The carbon content in steel is no more than 2.14% by weight. Higher carbon content results in harder and stronger steel, but it becomes more brittle and prone to breaking, making it less malleable. Conversely, lower carbon content increases ductility. What is Carbon Steel? Carbon steel primarily consists of iron and carbon, with other elements present in very small, almost negligible amounts. Despite having only two main elements, carbon steel can be produced in numerous ways with various applications by adjusting the carbon content, depending on its intended use. Based on carbon content: Low carbon steel: carbon content ≤ 0.25% Medium carbon steel: carbon content 0.25% – 0.6% High carbon steel: carbon content 0.6% – 2% What is Structural Carbon Steel?  This group of steel has higher quality than regular quality steel, reflected in its lower content of harmful impurities (S ≤ 0.04%, P ≤ 0.035%), precise carbon content, and clearly defined mechanical properties.  Structural carbon steel is detailed in guides that list both composition and mechanical properties. It is used in manufacturing high-stress machine parts such as gears, worms, cams, and springs. According to Vietnamese standards (TCVN), structural carbon steel is designated by the letter C, followed by a number indicating the carbon content. For example, C20, C45, C65, etc. Example: C45, where C denotes carbon steel, and 45 indicates 0.45% carbon content. International Designations: Japan (JIS): Designated as SxxC, where xx indicates the carbon content percentage. For example, S45C has 0.45% carbon. USA (AISI/SAE): Designated as 10xx, where xx indicates the carbon content percentage. For example, 1045 has 0.45% carbon. What is CT3 Steel? CT3 steel is a type of low carbon structural steel in group C, with a tensile strength rating of 8. It is primarily used in the manufacturing of machine parts, molds, and metal plates, and has many applications in construction, steel structures, ports, metalworking, and machinery components. CT stands for low carbon, and 3 indicates that it is a structural steel in group C. According to the TCVN 1765 – 75 standard for steel grades, group C includes designations like CCT34, CCT38, etc. The numbers following 3 (specifically 4, 8) indicate the steel’s tensile strength. What is Tool Carbon Steel? Tool carbon steel is a type of steel with high carbon content (0.7 – 1.4%) and low levels of impurities such as sulfur (S) and phosphorus (P) (< 0.025%). Although tool carbon steel has high hardness when heat-treated, it has low heat resistance, making it suitable for use in tools like chisels, files, measuring instruments, and various stamping dies. According to Vietnamese standards (TCVN), tool carbon steel is designated by the letters CD, followed by a number indicating the carbon content per ten thousand, such as CD70, CD80, CD100. Example: CD100 – where CD stands for tool carbon steel, and 100 indicates 1% average carbon content. What is Alloy Steel? Alloy steel contains, in addition to the two main elements, a combination of other elements ranging from 1% to 50% to alter the mechanical properties of the product. Based on the total content of additional metal elements, alloy steel is classified into: Low alloy steel: total content of other metal elements ≤ 2.5% Medium alloy steel: total content of other metal elements 2.5% – 10% High alloy steel: total content of other metal elements > 10% In construction and domestic applications, low alloy steel is commonly used. Low alloy steel typically includes elements such as manganese, chromium, silicon, nickel, etc., in amounts not exceeding 10%. Each alloy element added to steel has a different function: Chromium (Cr): The main component in creating stainless steel, with a chromium content ranging from 10.5% to 26%. Nickel (Ni): Enhances the strength and toughness of the steel. Manganese (Mn): Added to steel to deoxidize during melting, preventing the formation of iron sulfide impurities that can cause steel to crack. Manganese content is only 0.5% to 0.8%. Silicon (Si) and Copper (Cu): Added in small amounts to resist sulfuric acid (H2SO4) corrosion. Nitrogen (N): Increases the strength of the steel. Molybdenum (Mo): Added to prevent pitting and cracking corrosion. Sulfur (S): Improves machinability, but only a small amount is added to avoid sulfur brittleness.

Simulation and Analysis: Using CAE (Computer-Aided Engineering) tools, the design is simulated to analyze stress, thermal, and dynamic behaviors. This step helps in identifying potential issues before physical prototyping. Prototyping: A physical prototype is created, often using 3D printing or initial CNC machining. This prototype is tested for fit, form, and function, allowing for design adjustments before full-scale production. Material Selection Material Requirements: The selection of materials is based on the part’s requirements, such as strength, weight, heat resistance, and corrosion resistance. Common Materials: Commonly used materials include steel for strength, aluminum for lightweight components, and various plastics for non-structural parts. High-performance parts may use advanced materials like carbon fiber composites. Material Procurement: Once selected, the materials are sourced from suppliers, ensuring they meet the required quality standards and specifications. Manufacturing CNC Programming: The CAD model is converted into a CNC program using CAM (Computer-Aided Manufacturing) software. This program contains the instructions for the CNC machine to follow, including tool paths, cutting speeds, and feed rates. Setup: The proper fixtures and tooling are installed on the CNC machine.The raw material is firmly fixed in position. Machining Process: The CNC machine precisely cuts, drills, mills, or turns the material into the desired shape. Depending on the complexity of the part, multiple CNC processes may be used. CNC Milling: Used for creating complex shapes and features such as slots, holes, and contours. CNC Turning: Used for producing cylindrical parts such as shafts and bolts. CNC Drilling: Used for creating precise holes in the parts. Finishing Operations: Post-machining processes like deburring, polishing, and coating are applied to achieve the final surface finish and meet aesthetic and functional requirements. Quality Control and Testing Inspection: Each part undergoes rigorous inspection using precision measuring tools and instruments such as calipers, micrometers, and CMMs (Coordinate Measuring Machines) to ensure it meets the specified dimensions and tolerances. Functional Testing: Parts are tested for functionality under simulated operating conditions. For example, engine components may be subjected to thermal and stress tests to ensure they can withstand real-world conditions. Compliance Checks: Parts are checked for compliance with industry standards and regulations, ensuring

Everything You Need to Know about Gear

Gears are fundamental components in a wide array of mechanical systems, serving as the backbone for transferring and modifying motion and force in countless machines. From the intricate inner workings of a wristwatch to the powerful transmission systems in automobiles, gears are indispensable in our daily lives.  Understanding gears—how they function, their various types, and their practical applications—provides valuable insight into the mechanics that power modern technology.  In this comprehensive guide, MaTec Vietnam will help you delve into the essentials of gears, exploring their design, operation, and significance in various industries, ensuring you have all the knowledge you need about these pivotal mechanical elements. What is Gear and Importance of Gear? What is Gear? A gear is a rotating machine element with cut teeth or cogs that mesh with another toothed part to transmit torque. Gears alter the speed, torque, and direction of a power source. They are fundamental in mechanical devices, enabling complex motion and force transfer with precision.  Gears are found in numerous applications, from clocks and bicycles to car transmissions and industrial machinery, making them crucial components in the engineering and mechanics fields. Importance of Gear Power Transmission Gears are fundamental to power transmission in mechanical systems. They enable the transfer of rotational force between different parts. The meshing of gears ensures efficient torque transmission, delivering the desired output effectively. Speed Reduction and Amplification Gears allow for the modification of rotational speed, which is vital in many applications. By adjusting the number of teeth on the gears, systems can either reduce or increase the input speed to match the required output speed. This flexibility is essential for tailoring the speed of operation. Torque Multiplication One of the most significant advantages of gears is their ability to multiply torque. By using gears of varying sizes, it is possible to increase or decrease the input torque. This capability is especially beneficial in applications like heavy machinery or vehicles, which require substantial torque. Directional Changes Gears are often employed to change the direction of motion in mechanical systems. Specific arrangements, such as bevel or worm gears, can redirect rotational motion at different angles. This functionality enables the creation of complex systems that can transmit motion in multiple directions. Synchronization of Components Many machines and devices rely on gears to synchronize the movement of different components. Multiple gears working together ensure that various parts move in unison. This synchronization is crucial for achieving smooth, coordinated operations. In summary, gears are indispensable in mechanical systems for their roles in power transmission, speed adjustment, torque multiplication, directional changes, and synchronization of components. Types of Gears and Their Applications There exists a variety of gear types, each possessing distinct characteristics and suitable applications. Below are the four primary types of gears that are essential to understand: Spur Gears Spur gears are the simplest and most common type of gear, featuring cylindrical teeth aligned parallel to the gear’s axis. They offer efficient power transmission and are cost-effective to produce due to their straightforward design. Spur gears are typically employed in applications where noise is not a concern, such as electric drills, conveyor systems, and washing machines. Helical Gears Helical gears have angled teeth arranged in a helix pattern around the gear’s circumference. When opposed to spur gears, its helical shape allows for quieter and more seamless operation. The gradual engagement of teeth reduces impact forces and enhances load-bearing capacity. Helical gears find widespread use in industries such as automotive transmissions, industrial machinery, and power generation. Bevel Gears The purpose of bevel gears is to transfer motion and power between shafts that intersect. They feature conical-shaped teeth and come in two main types: straight bevel gears and spiral bevel gears. Straight bevel gears, with straight teeth, are suitable for low-speed applications. In contrast, spiral bevel gears, with curved teeth, excel in high-speed and heavy-duty applications such as automotive differentials, marine propeller drives, and locomotives. Worm Gears Worm gears consist of a worm (a threaded shaft) and a gear (commonly known as a worm wheel). The worm teeth mesh with the gear teeth, enabling significant gear reductions and high torque transmission. Worm gears are renowned for their self-locking properties, preventing back-driving by the worm. They are ideal for applications requiring holding power or preventing reverse motion, such as lift mechanisms, conveyor systems, and steering wheels. Five Gear Design Categories Gears come in various styles and designs, each tailored to specific applications. Here are five key gear categories explored: External Gears External gears, also known as spur gears, are the most common and widely used type. They feature cylindrical gears with teeth positioned on the outer circumference. These gears have teeth parallel to the gear axis and engage with the teeth of other external gears to transmit power efficiently.  External gears are valued for their simplicity, cost-effectiveness, and reliability, making them ideal for applications such as automotive transmissions, industrial machinery, consumer appliances, and power tools. Internal Gears Internal gears have teeth around their inner circumference and mesh with an external gear of larger diameter. They offer advantages including compactness, torque transmission, and load distribution. Compared to external gears, internal gears can handle higher loads and provide smoother operation due to their larger number of engaged teeth. They are commonly used in applications with limited space, such as planetary gear systems, gear pumps, certain gear reducers, and automotive parts. Rack and Pinion Gears Rack and pinion gears combine a linear gear (rack) with a cylindrical gear (pinion). The rack features straight teeth, while the pinion meshes with the rack to convert rotational motion into linear motion. Widely used in applications requiring precise linear movement, such as steering systems, machine tools, linear actuators, and various industrial machinery. Planetary Gears Planetary gears, also known as epicyclic gears, are highly flexible and efficient gear systems. They consist of a central gear called the sun gear, multiple planet gears that mesh with the sun gear, and an outer ring gear or annulus.  Planetary gears offer advantages such as high power density, compactness,

What is The Difference Between 3D Printing vs CNC Machining

In the rapidly evolving world of manufacturing, two technologies stand out for their ability to produce intricate and precise parts: 3D printing vs CNC machining. While both methods aim to create high-quality components, they operate on fundamentally different principles. 3D printing, an additive process, builds objects layer by layer from a digital file, offering unparalleled design flexibility.  On the other hand, CNC machining is a subtractive process that shapes parts by removing material from a solid block using precision tools. Understanding the key differences between these two methods is crucial for selecting the right technology for your manufacturing needs.  This article, MaTec Vietnam will delves into the specifics of 3D printing vs CNC machining, comparing their advantages, limitations, and ideal applications. What is 3D Printing? 3D printing is a collection of processes that share a common approach to manufacturing. This technique involves creating virtual models of three-dimensional parts, which are rendered by software as a series of slices. The thickness of these slices is tailored to the specific machine or setting being used. Each layer is printed sequentially, and the stacking and bonding of these slices enable the construction of a complete part from these finite 2D steps. Various materials can be used in 3D printing, including extruded polymer filaments, light-sensitive resins, laser-melted powders, filament feedstock, waxes, and even biological materials. To achieve a successful print, several tools must work together, including a CAD package to design the part and save it as an STL file, slicer software to convert the 3D file into a sequence of 2D machine instructions, and the 3D printer itself. The first commercially viable 3D printing systems emerged in the late 1980s, and since then, the technology has rapidly expanded in both methods and materials. Compared to CNC machining, 3D printing offers better cosmetic finishes and more efficient material usage. It also eliminates the need for direct manual labor in producing complex parts. What Benefits Does 3D Printing Offer Over CNC Machining? Speed of Production 3D printing can produce net shape parts quickly, without the need for extensive setup or manual programming, which is typically required for CNC machining. Cost Efficiency 3D printing is generally more cost-effective for creating complex net shapes. It involves minimal setup and operational intervention, often making CNC components up to ten times more expensive than 3D printed parts. Ease of Use Modern 3D printers are becoming more office-friendly and require only modest skills for setup and maintenance. They are increasingly capable of meeting a wide range of needs. In contrast, CNC machining remains a heavy-engineering process that requires highly skilled operators and ongoing training to maintain proficiency. What Are the Cons of 3D Printing Compared to CNC Machining? Material Strength 3D printing processes can result in varied material strengths compared to the native properties of the materials. For instance, Fused Filament Fabrication (FFF) in ABS may achieve as low as 10% of the material’s ultimate tensile strength (UTS), while Selective Laser Sintering (SLS) in nylon can achieve up to 100%. In contrast, CNC machining produces parts from solid, undisturbed materials, typically resulting in higher strength. Dimensional Accuracy While 3D printing can achieve good dimensional accuracy, it may struggle with high precision requirements. CNC machining, on the other hand, is highly precise and can attain improved accuracy by adjusting the processing speed. Surface Finish 3D printing often faces challenges with surface finish due to process mechanics, particularly Z-resolution, which can cause stepped surfaces and visual imperfections. CNC machining produces parts with a uniform and highly precise surface finish, provided that cutter paths are well-programmed for smooth results. What is CNC Machining? CNC machining is a computerized manufacturing process that uses pre-programmed software and codes to control the movement of machine tools. This technology employs a variety of complex machinery, such as lathes, mills, and grinders, to accurately and precisely cut, create, and shape different parts.  The first CNC machine was developed by James Parson in 1949, focusing on producing helicopter and aircraft blades. In 1958, Richard Kegg and MIT introduced the first CNC milling machine. Though CNC machining involves a complex setup and can be costly, it is preferred for parts that require long-term wear properties, strength, smooth surface finish, and high precision, making it superior to 3D printing in these aspects. Figure 2 below illustrates an example of a CNC milling machine. Read more: What is Precision Machining? What Are the Pros of CNC Machining Compared to 3D Printing? Material Integrity CNC machining uses engineering materials in their undisturbed, native state, ensuring that parts retain the full properties of these materials. In contrast, 3D printing often utilizes materials that are weaker approximations of their traditional counterparts. Precision CNC machining produces parts with higher precision, as it can maintain tighter tolerances compared to the tolerances achievable with 3D printing. What Are the Cons of CNC Machining Compared to 3D Printing? Tooling Requirements CNC machining often necessitates the creation of mounting tools, complicating the setup process. In contrast, 3D printing allows for the creation of free-floating parts built directly on a table or scaffold, simplifying production. Material Waste CNC machining is a subtractive process that removes excess material, resulting in significant waste. Conversely, 3D printing is an additive process that minimizes waste by using only the material necessary to build the part. What is The Difference Between 3D Printing vs CNC Machining Attribute 3D Printing CNC Machining Material Availability Limited Unlimited Design Flexibility Not constrained by process limitations Limited by cutting capabilities, tool access, tool paths, minimum radius defined by axes, and repositioning needs Precision Varies from 0.016 to 1 mm+, typically around 0.2 mm High precision at 0.005 mm, achievable with slow feed rates, new cutting tools, and shallow cuts Operator Skill Generally low Very high Build Speed Low setup time but builds often take hours Potentially high setup and programming time; cutting phase is very fast Surface Finish Grainy, rough, and stepped; features often blurred Can achieve very high-quality surface finish with longer cutting times Strength Typically 10-20% of

How to Calculate RPM for Milling Cutters

Understanding how to calculate RPM for milling cutters is crucial in machining. It ensures precision, prolongs tool life, matches the speed to the material being cut, promotes safety, and enhances efficiency and productivity. By mastering RPM calculation, machinists can achieve consistent quality, reduce costs, and optimize their machining processes for maximum effectiveness. Now, let’s explore how to calculate RPM for Milling Cutters with MaTec Vietnam. What is RPM RPM, or Revolutions Per Minute, is a unit of measurement used to quantify the rotational speed of an object around its axis within a specific timeframe, usually one minute. It provides crucial information about how fast an object, such as a milling cutter, is rotating during a machining operation. In the context of milling cutters, RPM indicates how many complete revolutions the cutter makes in one minute while cutting into a workpiece. This metric directly influences the cutting speed and efficiency of the milling process. Calculating the appropriate RPM for milling cutters involves considering various factors such as the cutter’s diameter, the type of material being machined, the desired cutting speed, and the characteristics of the milling machine itself. Adjusting the RPM allows machinists to tailor the cutting process to achieve optimal results for a particular machining task. For instance, higher RPM values result in faster cutting speeds, which can be advantageous for materials that allow for high-speed machining, such as aluminum. On the other hand, machining harder materials like steel might require lower RPM to prevent excessive heat buildup and tool wear. How to Calculate RPM for Milling Cutters In milling operations, determining the appropriate RPM (Revolutions Per Minute) for the milling cutter is essential for achieving optimal cutting speed and extending the cutter’s lifespan. The RPM is calculated based on the cutter’s diameter and the cutting speed of the material being processed. The following formula may be used to determine RPM: RPM = (Cutting Speed * 4) / Diameter of the Cutter For example, if the cutting speed for mild steel is 100 feet per minute and the cutter’s diameter is 0.4 inches, the RPM would be: RPM = (100 * 4) / 0.4 = 1000 It’s important to note that these calculations serve as guidelines and may require adjustments depending on specific machine settings, material properties, and cutting conditions. A higher RPM isn’t always advantageous, as it can lead to overheating and premature wear of the cutter. Conversely, a lower RPM may result in ineffective cutting and a subpar surface finish. Example of RPM Calculation: Cutter Diameter Cutting Speed (Feet per Minute) RPM 0.4 inches 100 1000 Understanding and accurately applying the RPM calculation is crucial for maximizing productivity and preserving the milling cutter’s longevity. This careful balance between speed, efficiency, and durability forms an integral aspect of successful milling operations. Do Milling Cutters Influence End-Part Tolerances? Absolutely, milling cutters play a pivotal role in attaining the desired tolerances for machined parts. Tolerance in machining refers to the acceptable range of variation in the physical dimensions of a finished product. The selection of milling cutter type, size, material, and cutting conditions collectively impact the precision of the machining process and the final part outcome. Each milling cutter is engineered for specific milling operations, and its choice significantly impacts the accuracy and surface finish of the machined part. A well-suited milling cutter, appropriately utilized, can facilitate achieving tight tolerances in the milled part and minimizing deviations from specified dimensions. Here’s a breakdown of typical dimensional tolerances (in millimeters) associated with various types of milling cutters: Types of Milling Cutters Typical Dimensional Tolerances(in mm) End Mills ± 0.01 – ± 0.05 Face Mills ± 0.02 – ± 0.05 Slab Mills ± 0.02 – ± 0.07 Fly Cutters ± 0.01 – ± 0.05 Form Milling Cutters ± 0.01 – ± 0.04 Hollow Mills ± 0.02 – ± 0.06 (Note: Values are approximations. Actual achievable tolerances may vary depending on factors like cutter quality, machine stability, workpiece material properties, and cutting conditions.) Milling cutter geometry, material composition, and any applied coatings also wield significant influence. For instance, cutters with sharp edges and premium coatings can mitigate cutting forces, reducing the risk of part distortion and enhancing dimensional precision.

Aluminum CNC Machining | Benefits of Using Aluminum for CNC Machined Parts

Aluminum CNC machining involves using computer numerical control (CNC) machines to precisely cut and shape aluminum into various components and parts. This process is highly efficient and allows for high levels of accuracy, making it ideal for producing intricate designs and complex geometries.  Aluminum’s lightweight, strength, and corrosion resistance make it a popular choice in industries such as aerospace, automotive, and electronics. CNC machining of aluminum ensures high-quality finishes, tight tolerances, and consistent repeatability, making it a preferred method for both prototyping and mass production. In this article, MaTec Vietnam will help you explore Aluminum in CNC Machining industries in detail. What is Aluminum Aluminum is one of the most commonly machined materials today, second only to steel in terms of machining frequency. This is primarily due to its excellent machinability. In its purest form, aluminum is a soft, ductile, non-magnetic, silvery-white metal.  It is rarely utilized in its purest form, though. Instead, aluminum is often alloyed with elements like manganese, copper, and magnesium to create hundreds of aluminum alloys, each with significantly enhanced properties. Aluminum’s Advantages for CNC Machined Parts Although there are numerous aluminum alloys with varying properties, several fundamental characteristics apply to almost all aluminum alloys. Machinability Aluminum is easily formed, worked, and machined using various processes. Its softness allows it to be quickly and easily cut by machine tools, and it chips easily, making it less expensive and requiring less power to machine than steel.  These characteristics benefit both the machinist and the customer ordering the part. Additionally, aluminum’s good machinability means it deforms less during machining, leading to higher accuracy and enabling CNC machines to achieve tighter tolerances. Strength-to-Weight Ratio Aluminum has about one-third the density of steel, making it relatively lightweight. Aluminum is quite strong while being lightweight. This combination, known as the strength-to-weight ratio, makes aluminum ideal for parts in industries such as automotive and aerospace, where both strength and low weight are crucial. Corrosion Resistance Aluminum is resistant to scratching and corrosion in common marine and atmospheric conditions. These properties can be further enhanced by anodizing. It’s important to note that corrosion resistance varies among different aluminum grades, but the most commonly CNC machined grades generally offer excellent resistance. Performance at Low Temperatures Many materials lose their desirable properties at sub-zero temperatures; for example, carbon steels and rubber become brittle. In contrast, aluminum retains its softness, ductility, and strength even at very low temperatures. Electrical Conductivity Pure aluminum has an electrical conductivity of about 37.7 million siemens per meter at room temperature. While aluminum alloys may have lower conductivities than pure aluminum, they are still conductive enough for use in electrical components.  However, if electrical conductivity is not a desirable characteristic for a machined part, aluminum may not be the best choice. Recyclability CNC machining processes generate a significant amount of waste material in the form of chips. Aluminum is highly recyclable, requiring relatively low energy, effort, and cost to recycle. This recyclability is beneficial for reducing material wastage and makes aluminum a more environmentally friendly material to machines. Anodization Potential Anodization, a surface finishing process that increases wear and corrosion resistance, is easily achievable with aluminum. This process also simplifies adding color to machined aluminum parts. Popular Alloys in Aluminum for CNC Processing Based on our experience at MaTec Vietnam, the following aluminum grades are among the most frequently used for CNC machining: EN AW-2007 / 3.1645 / AlCuMgPb Alternative designations: 3.1645, EN 573-3, AlCu4PbMgMn. This aluminum alloy contains 4-5% copper as its main alloying element. It is a short-chipped, durable, lightweight alloy with high mechanical properties similar to AW 2030. It is suitable for threading, heat treatment, and high-speed machining, making it ideal for producing machine parts, bolts, rivets, nuts, screws, and threaded bars. However, it has low weldability and corrosion resistance, so protective anodizing is recommended after machining. EN AW-5083 / 3.3547 / Al-Mg4.5Mn Alternative designations: 3.3547, Alloy 5083, EN 573-3, UNS A95083, ASTM B209, AlMg4.5Mn0.7. AW 5083 is known for its excellent performance in harsh environments. It contains magnesium and traces of chromium and manganese, offering high resistance to corrosion in chemical and marine environments. It has the highest strength of all non-heat treatable alloys, retaining this property even after welding. Although it should not be used in temperatures above 65°C, it excels in low-temperature applications, making it suitable for cryogenic equipment, marine applications, pressure equipment, chemical applications, welded constructions, and vehicle bodies. EN AW-5754 / 3.3535 / Al-Mg3 Alternative designations: 3.3535, Alloy 5754, EN 573-3, UNS A95754, ASTM B209, Al-Mg3. AW 5754 is a wrought aluminum-magnesium alloy with the highest percentage of aluminum. It may be forged, extruded, and rolled.  It is non-heat treatable but can be cold-worked to increase strength at the cost of ductility. This alloy has excellent corrosion resistance and high strength, making it popular for CNC machining in welded structures, flooring applications, fishing equipment, vehicle bodies, food processing, and rivets. EN AW-6060 / 3.3206 / Al-MgSi Alternative designations: 3.3206, ISO 6361, UNS A96060, ASTM B221, AlMgSi0.5. This magnesium and silicon-containing wrought aluminum alloy is heat-treatable with average strength, good weldability, and good formability. It is highly resistant to corrosion, which can be further improved through anodizing. Construction, food processing, medical equipment, and automobile engineering are among industries that often employ EN AW 6060. EN AW-7075 / 3.4365 / Al-Zn6MgCu Alternative designations: 3.4365, UNS A96082, H30, Al-Zn6MgCu. The main alloying ingredient in this grade is zinc. EN AW 7075 has average machinability, poor cold forming properties, and is unsuitable for welding and soldering. However, it has a high strength-to-density ratio, excellent resistance to atmospheric and marine environments, and strength comparable to some steel alloys. This alloy is used in a wide range of applications, including hang glider and bicycle frames, rock climbing equipment, weaponry, and mold tool manufacturing. EN AW-6061 / 3.3211 / Al-Mg1SiCu Alternative designations: 3.3211, UNS A96061, A6061, Al-Mg1SiCu. Containing magnesium and silicon as its major alloying elements with trace amounts of copper, this high-strength alloy (tensile strength of 180 MPa)
