ALUMINUM ALLOY SUITABLE FOR HIGH PRESSURE DIE CASTING

摘要

Copper-free aluminum alloys suitable for high pressure die casting and capable of age-hardening under elevated temperatures are provided. The allow includes about 9.5-13 wt % silicon, about 0.2 to 0.6 wt % Magnesium, about 0.1 to 2 wt % iron, about 0.1 to 2 wt % manganese, about 0.1 to 1 wt % nickel, about 0.5 to 3 wt % zinc, and 0 to 0.1 wt % strontium, with a balance of aluminum. Methods for making high pressure die castings and castings manufactured from the alloy are also provided.
