    摘要： Disclosed is a method for making an aluminum alloy sheet having controlled levels of strength properties for forming into a container panel. A body of an aluminum alloy consisting essentially of 0.3 to 0.6 wt.% Cu, 1.1 to 1.7 wt.% Mg, 0.3 to 0.6 wt.% Si, 0.3 to 0.55 wt.% Fe, 0.5 to 1.2 wt.% Mn, the remainder aluminum, incidental elements and impurities, is hot rolled to a gauge in the range of 0.12 to 0.16 inch to provide a hot rolled product. The hot rolled product is cold rolled to provide a reduction of 50 to 80% in thickness, then solution heat treated in a range of 850 to 1100°F and rapidly cooled before cold rolling to a final sheet gauge by providing a reduction of 30 to 90% in thickness.

    摘要： An alloy product having improved combinations of strength, density, toughness and corrosion resistance, consists essentially of about 7 to 12% zinc, about 1.5 to 2.7% magnesium, about 1.75 to 3% copper, one or more elements selected from 0.05 to 0.2% zirconium, 0.05 to 0.4% manganese, 0.03 to 0.2% vanadium and 0.03 to 0.5% hafnium, the total of said elements not exceeding about 1%, the balance aluminum and incidental elements and impurities. A preferred product consists essentially of about 7.6 to 8.6% zinc, about 1.6 to 2.2% magnesium, about 2 to 2.8% copper and at least one element selected from zirconium, vanadium and hafnium present in an amount not exceeding about 0.2%, the balance aluminum and incidental elements and impurities. The alloy product is suitable for aerospace applications.

    摘要： Rolled plate products up to 6 inches thick or more and other products in an aluminum alloy consisting essentially of about 5.2 to 6.8% zinc, 1.7 to 2.4% copper, 1.6 to 2% magnesium, 0.03 to 0.3% zirconium, balance substantially aluminum and incidental elements and impurities, are useful in making structural members for commercial airplanes especially by machining or shaping such members from the plate. Such members include lower wing skins (18) and wing spars (20) and other members. The plate is made by operations comprising homogenization, hot rolling, solution heat treatment, stretching and artificial aging. Alternatively, the plate is shaped after stretching, which may include machining, and is then artificially aged.
