At Kurt Die Casting, we focus on aluminum die casting with A380 and A360 alloys, but have the capacity and capability to add more per request.
A380 is a popular aluminum alloy used in die casting. It is part of the aluminum-silicon family of alloys and is known for its excellent combination of strength, hardness, and corrosion resistance. The A380 alloy typically contains aluminum, silicon, copper, iron, and other elements in varying proportions. It is widely used in the automotive industry for casting components such as engine housings, transmission cases, and other structural parts.
A360 is an aluminum alloy with excellent pressure tightness and fluidity. It has a high silicon content and offers high corrosion resistance as well as high strength, even in elevated temperatures.
413: Very high silicon content, good fluidity but with poor anodizing quality.
ZA-27 Zinc Alloy: Is 1.5 to 3 times stronger than cast aluminum and has the tensile strength of grey or malleable cast iron. Machinability is very good to excellent.
