NEW HIGH PRESSURE DIE CASTING ALUMINUM ALLOY FOR HIGH TEMPERATURE AND CORROSIVE APPLICATIONS

摘要

Copper-free aluminum alloys suitable for high pressure die casting and capable of age-hardening under elevated temperatures. The alloy includes about 7-15 wt % silicon, about 0 to 0.6 wt % magnesium, about 0 to 1.0 wt % iron, about 0 to 1.0 wt % manganese, about 0 to 1.0 wt % zinc, about 0 to 0.1 wt % strontium, about 0 to 0.5 wt % titanium, about 0 to 0.5 wt % zirconium, about 0 to 0.5 wt % vanadium, about 0 to 0.5 wt % copper, and about 0 to 1.0 wt % nickel, with a balance of aluminum. Methods for making high pressure die castings and castings manufactured from the alloy.
