Abstract

An improved aluminum alloy for casting into a component, such as a vehicle component, is provided. The aluminum alloy preferably includes at least 80 weight percent (wt. %) aluminum; 9.5 to 11.5 wt. % silicon; 1.5 max wt. % zinc; 0.1 wt. % to 0.6 wt. % magnesium; 0.10 wt. % to 0.60 wt. % copper; 0.2. to 0.6 wt. % manganese; 0.2 wt. % to 0.6 wt. % iron; 0.01 wt. % to 0.07 wt. % strontium; and up to 0.15 wt. % titanium, based on the total weight of the aluminum alloy. This improved aluminum alloy can be formed by combining recycled aluminum or a recycle aluminum alloy with at least one additional element. The cast component formed of the aluminum alloy has a yield strength of 100 to 120 MPa and an elongation of 10% to 20% when the cast component is in the T7 temper condition
