    摘要: An automobile component including an aluminum alloy product having a base aluminum alloy layer and a first additional aluminum alloy layer disposed directly on the base layer. The base aluminum alloy layer includes 2.0 to 22 wt. % zinc and the zinc is a predominate alloying element of the base layer other than aluminum and the first additional aluminum alloy layer 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. The automobile component may include outer panel sections, high form inner sections, reinforcement sections, crash sections, large flat panel sections, and high strength sections and, 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.
