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.

Crashworthy structures formed of multilayered metallic materials

A tie down assembly adapted to be installed within a structure includes a cup and a crossbar that is fastened removably to the cup by a plurality of fasteners. The cup includes a recess forming an interior surface, and a plurality of seats extending from the interior surface. The crossbar includes a central portion and a plurality of elongated members extending therefrom. Each of the members includes a head that engages a corresponding one of the seats of the cup and is secured to the seat by one of the fasteners. The central portion of the crossbar may include a central aperture that receives one of the fasteners for an additional attachment point to the cup. The crossbar is adapted to receive tie down hooks, connectors, and the like. When the crossbar requires repair or replacement, it may be removed from the cup by unfastening the fasteners without the need to remove the cup from the structure.

Tie down assembly

A tie down assembly adapted to be installed within a structure includes a cup and a plate fastened removably to the cup by fasteners. The cup includes a first sidewall, an interior portion, and a plurality of seats that extends within the interior portion. The plate an aperture to receive tie down connectors. The plate includes a plurality of tabs. The plate is positioned within the interior portion of the cup and rests on the seats. When the plate requires repair or replacement, it may be removed from the cup by unfastening the fasteners without the need to remove the cup from the structure. Each of the tabs of the plate is positioned within a space between adjacent pairs of the seats of the cup and is adapted to engage the seats of the cup so as to inhibit rotation of the plate relative to the cup.
