Abstract
An improved aluminum alloy for blending with a recycled aluminum alloy to form a material for high pressure vacuum die casting is provided. The improved aluminum alloy includes 10 to 12 wt. % silicon, 0.65 to 0.85 wt. % manganese, less than 0.05 wt. % iron, less than 0.05 wt. % magnesium, 0.2 to 0.4 wt. % strontium, less than 0.05 wt. % titanium, and less than 0.02 wt. % copper, based on the total weight of the improved aluminum alloy. The recycled aluminum alloy typically includes 0.60-1.0 wt. % silicon, ≤0.35 wt. % iron, ≤0.20 wt. % copper, 0.05-0.20 wt. % manganese, 0.40-0.8 wt. % magnesium, ≤0.20 wt. % chromium, ≤0.15 wt. % zinc, ≤0.05 wt. % titanium, ≤0.05 wt. % others (each), and ≤0.15 wt. % others (total). The material meets the specifications for an Aural 5S alloy.
