摘要： A method of producing an aluminum product having high formability, high fracture toughness, high strength and improved corrosion resistance, the method comprising: (a) providing stock including an aluminum base alloy consisting essentially of about 0.7 to 1.0 wt.% silicon, not more than about 0.3 wt.% iron, not more than about 0.5 wt.% copper, about 0.8 to 1.1 wt.% magnesium, about 0.3 to 0.4 wt.% manganese, and about 0.5 to 0.8 wt.% zinc, the remainder substantially aluminum, incidental elements and impurities; (b) homogenizing the stock; (c) hot rolling; (d) solution heat treating; (e) cooling by quenching; and (f) artificially aging to produce a T6 temper in the aluminum product. The figure shows ductility loss as a function of the amount of copper in alloys containing either manganese or chromium and zinc relative to alloy 6013.

摘要： A method of producing an aluminum product comprising: providing stock including an aluminum alloy comprising about 4.0 to 4.4 wt.% copper, about 1.25 to 1.5 wt.% magnesium, about 0.35 to 0.5 wt.% manganese, not more than 0.12 wt.% silicon, not more than 0.08 wt.% iron, not more than 0.06 wt.% titanium, the remainder substantially aluminum, incidental elements and impurities; hot working the stock; annealing; cold rolling; solution heat treating; cooling; holding for at least 12 hours at room temperature; and cold working from about 4 % to 7 % thereby producing a product having increased strength and toughness properties. The figure shows composition-phase relations for an Al-Cu-Mg system at 930 °F.

摘要： High strength aluminum alloys based on the Al-Zn-Mg-Cu alloy system preferably include high levels of zinc and copper, but modest levels of magnesium, to provide increased tensile strength without sacrificing toughness. Preferred ranges of the elements include by weight, 8.5-10.5% Zn, 1.4-1.85 % Mg, 2.25-3.0% Cu and at least one element from the group Zr, V, or Hf not exceeding about 0.5%, the balance substantially aluminum and incidental impurities. In addition, small amounts of scandium (0.05-0.30%) are also preferably employed to prevent recrystalization. During formation of the alloys, homogenization, solution heat treating and artificial aging processes are preferably employed.

摘要： Al-Mg-Sc based alloys include additional elements selected from the group comprising Hf, Mn, Zr, Cu and Zn to improve their tensile properties. The alloys are preferably comprised of aluminum and, in wt.%, 1.0-8.0 % Mg, 0.05-0,6 % Sc, 0.05-0.20 % Hf and/or 0.05-0.20 % Zr, and 0.5-2.0 % Cu and/or 0.5-2.0 % Zn. In addition, 0.1-0.8 wt.% Mn may be added to the alloy to improve its strength characteristics further.
