    Abstract: Aluminum alloy products having improved ballistics performance are disclosed. The aluminum alloy products may be underaged. In one embodiment, the underaged aluminum alloy products realize an FSP resistance that it is better than that of a peak strength aged version of the aluminum alloy product. In one embodiment, ballistics performance criteria is selected and the aluminum alloy product is underaged an amount sufficient to achieve a ballistics performance that is at least as good as the ballistics performance criteria.

    Abstract: There is claimed an aerospace alloy having improved corrosion resistance performance, particularly intergranular corrosion resistance. The alloy consisting essentially of: about 0.6-1.15 wt. % silicon, about 0.6-1.0 wt. % copper, about 0.8-1.2 wt. % magnesium, about 0.55-0.86 wt. % zinc, less than about 0.1 wt. % manganese, about 0.2-0.3 wt. % chromium, the balance aluminum, incidental elements and impurities. While it is preferably made into sheet or plate product forms, it can also be extruded. Products made from this alloy exhibit at least about 5 % greater yield strength and about 45 % or greater resistance to intergranular corrosion attack than their 6013-T6 counterparts, as measured by average depth of corrosion after 24 hours exposure to an aqueous NaCl-H>2 2

    Abstract: High strength forged aluminum alloys and methods for producing the same are disclosed. The forged aluminum alloy products may have grains having a high aspect ratio in at least two planes, generally the L-ST and the LT-ST planes. The forged aluminum alloy products may also have a high amount of texture. The forged products may realize increased strength relative to conventionally prepared forged products of comparable product form, composition and temper.
