The Most Common Aluminum Alloys Used in Die Casting
In the die-casting industry, selecting the right aluminum alloy is crucial for producing high-quality parts with the necessary strength, durability, and precision. Aluminum alloys are widely favored in die casting due to their lightweight nature, excellent corrosion resistance, and strong mechanical properties. At CASS, we provide top-tier recycled aluminum alloys designed to meet the specific needs of die-casting manufacturers. Below are some of the most commonly used aluminum alloys in die casting and why they are popular choices.
1. Aluminum Alloy 380
Alloy 380 is one of the most commonly used aluminum alloys in die casting. It is popular because of its excellent balance of mechanical properties and cost-effectiveness. This alloy offers a good combination of strength, corrosion resistance, and thermal conductivity, making it ideal for a wide variety of applications, from automotive parts to electronic components. Its ease of casting and machinability also make it a preferred choice for manufacturers looking for efficiency in production.
Common uses: Transmission housings, engine components, furniture frames, and electronics.
2. Aluminum Alloy 383
For slightly better heat resistance and fluidity during casting, Alloy 383 is often used as an alternative to 380. It provides better corrosion resistance and is excellent for casting complex parts with thin walls, making it a go-to choice for intricate designs that require precision.
Common uses: Complex automotive parts, electrical housings, and consumer electronics.
3. Aluminum Alloy 413
Alloy 413 is another frequently used aluminum alloy in the die-casting world. This alloy is known for its exceptional pressure tightness, making it ideal for applications that require leak-proof or high-pressure parts. It also has excellent corrosion resistance, high thermal and electrical conductivity, and good castability.
Common uses: Hydraulic cylinders, engine blocks, and gear cases.
4. Aluminum Alloy A360
Alloy A360 is known for its superior corrosion resistance, excellent mechanical properties, and higher strength than the standard 380 alloy. It is commonly used when parts need to withstand higher stress or harsher environments. Although it can be slightly more difficult to cast, its performance in critical applications makes it a valuable option for manufacturers seeking long-lasting, high-performance parts.
Common uses: Engine components, transmission housings, and industrial equipment.
5. Aluminum Alloy 6061
While Alloy 6061 is more frequently used in extrusions than die casting, it can still be used in cast applications where its superior mechanical properties are required. This alloy is prized for its high strength-to-weight ratio and excellent corrosion resistance. It is also heat-treatable, providing increased strength and durability for demanding applications.
Common uses: Structural components, aerospace parts, and automotive frames.
6. Aluminum Alloy B390
Alloy B390 is well-known for its exceptional wear resistance and high hardness, making it perfect for components that endure a lot of friction. While it is less ductile than other alloys and more difficult to machine, its durability makes it ideal for certain automotive and industrial applications that require long-lasting parts under constant stress.
Common uses: Engine blocks, brake components, and automotive pumps.
Why Die Casters Rely on These Alloys
The die-casting process demands aluminum alloys that can handle high pressure, complex shapes, and varying levels of stress. Each alloy offers its own unique blend of characteristics, making it suited to specific applications. Whether the focus is on strength, corrosion resistance, or thermal conductivity, aluminum alloys provide the versatility needed to meet the demands of modern manufacturing.
