Aluminum is a primary metal in die casting, which in alloys is utilized for the cold-chamber die casting process. These aluminum alloys typically comprise elements such as magnesium, copper, and silicon.
Aluminum-based die casting alloys are a superb choice for intricate, finely detailed pieces as they are lightweight and provide excellent dimensional stability. They have robust resistance to temperature fluctuations, corrosion, electrical, and thermal conductivity. Here are some commonly used aluminum alloys for die casting.
- Aluminum Alloy 380: An all-purpose aluminum alloy with an equilibrium of castability and mechanical characteristics, 380 is widely used to make engine brackets, furniture, electronic enclosures, frames, handles, gearboxes, power tools, and more.
- Aluminum Alloy B390: This alloy has exceptional vibration and wear resistance. It’s commonly used for pump housings, valve bodies, and impellers.
- Aluminum Alloy 413: It possesses outstanding casting properties thanks to its high-pressure compressibility. AL413 is commonly applied in the making of architectural parts, food machinery, and hydraulic cylinders.
- Aluminum Alloy 443: Out of all the aluminum alloys used in die casting, AL443 provides the best ductility. This makes it perfect for consumer goods, particularly those that require plastic deformation after casting.
