Selecting the proper aluminum alloy for your high-pressure aluminum die casting application is an important task. Varying aluminum alloys are composed of many elements, including silicon, iron, copper, manganese, magnesium, nickel, zinc, tin, titanium, and others. For technical data specific to the chemical compositions and physical/mechanical properties of every aluminum alloy cast by RCM Industries, please see below.
Don’t know which alloy is best for your product or application? RCM’s team of engineers will work with you to make sure that the proper alloy is selected for your project. Although a variety of aluminum alloys can be die cast from primary or recycled aluminum, RCM Industries, Inc. has the capabilities to cast the following alloys:
- 380: 380 aluminum is the most common and cost effective aluminum alloy, providing the best combination of utility and cost. 380 aluminum also exhibits above average machining characteristics.
- 360: 360 aluminum selected for higher corrosion resistance, superior strength at elevated temperatures, and somewhat better ductility, but is more difficult to cast.
- 383: 383 aluminum is a modification of 380. It provides better die filling but with a moderate sacrifice in mechanical properties such as toughness.
- 390: 390 aluminum is selected for special applications where high strength, fluidity and wear-resistance and bearing properties are required. This alloy is optimal for many transmission applications. RCM’s Aallied Die Casting Company of Illinois division is a world leader in the production of 390 aluminum castings.
- 413: 413 aluminum is used for maximum pressure tightness and fluidity.
