Abstract:
1. An automobile component comprising: an aluminum alloy product, wherein the aluminum alloy product comprises: a base aluminum alloy layer and at least a first additional aluminum alloy layer disposed directly on the base layer; wherein the base layer has a first aluminum alloy composition; wherein the first aluminum alloy composition includes 2.0 to 22 wt. % zinc and the zinc is a predominate alloying element of the base layer other than aluminum; wherein the first additional aluminum alloy layer has a second aluminum alloy composition; wherein the second aluminum alloy composition includes 0.20 to 8.0 wt. % magnesium and the magnesium is a predominate alloying element of the first additional aluminum alloy layer other than aluminum; wherein the automobile component is selected from the group consisting of outer panel sections, high form inner sections, reinforcement sections, crash sections, large flat panel sections, and high strength sections; and wherein, when tested in a static axial crush test, a peak load of the automobile component increases at least 20% when compared to alloy 6014 in the T6 temper.
