  • Publication number: 20130270859
    Abstract: 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.

  • Publication number: 20110252956
    Abstract: In one embodiment, two or more layers of aluminum alloys are metallurgically bonded and then wrought to produce an armor product having improved ballistics limits for resistance to armor piercing and fragment simulated projectile threats. In one embodiment, the armor product can include a composition that includes a continuous gradient of two or more aluminum alloy compositions. In one embodiment, the armor product can include layers of different aluminum alloys. In one embodiment, the armor product can include compositions of a mixture of more than one aluminum alloy. This armor may be useful on light armor vehicles having wheels, as well as planes and boats.

  • Publication number: 20070000583
    Abstract: Aluminum sheet products having highly anisotropic grain microstructures and highly textured crystallographic microstructures are disclosed. The products exhibit improved strength and improved resistance to fatigue crack growth, as well as other advantageous properties such as improved combinations of strength and fracture toughness. The sheet products are useful for aerospace and other applications, particularly aircraft fuselages.
