Abstract

An improved aluminum alloy for casting into a component, such as a vehicle component, is provided. The improved aluminum alloy includes at least 80 wt. % aluminum; 6.0 to 8.0 wt. % silicon; 1.0 to 2.0 wt. % zinc; 0.10 to 0.6 wt. % magnesium; 0.1 to 0.60 wt. % copper; 0.20. to 0.60 wt. % manganese; up to 0.25 wt. % iron; 0.015 wt. % to 0.03 wt. % strontium; and up to 0.15 wt. % titanium, based on the total weight of the improved aluminum alloy. This improved aluminum alloy can be formed by combining recycled aluminum or recycled aluminum alloy with at least one additional element. The cast component formed of the improved aluminum alloy has a yield strength of 120 MPa to 130 MPa and an elongation of 8% to 16%, depending on flow length, when the cast component is in the as-cast (F temper) condition.
