Abstract: A high strength aluminum alloy is suitable for ultra thick gauge wrought product. The alloy can have 6 to 8 wt % zinc, 1 to 2 wt % magnesium, and dispersoid forming elements such as Zr, Mn, Cr, Ti, and/or Sc with the balance made of aluminum and incidental elements and/or impurities. The alloy is suitable for many uses, including in molds for injection-molded plastics.
Abstract: A rolled or forged Al—Zn—Cu—Mg aluminum-based alloy wrought product having a thickness from 2 to 10 inches. The product has been treated by solution heat-treatment, quenching and aging, and the product comprises (in weight-%): Zn 6.2-7.2, Mg 1.5-2.4, Cu 1.7-2.1. Fe 0-0.13, Si 0-0.10, Ti 0-0.06, Zr 0.06-0.13, Cr 0-0.04, Mn 0-0.04, Mn 0-0.04, impurities and other incidental elements ?0.05 each. Alloys per se and aircraft and aerospace uses, as well as methods of making products are also disclosed.

Abstract: The invention relates to a method for manufacturing a product comprising an AlCu alloy comprising (weight per cent): Cu: 3.8-5.5 Mg: 0.2-0.8 Mn: 0.2-0.6 Ag 0.2-0.5 Si<0.15 Fe<0.20 Zn<0.25 Cr<0.05 Zr<0.10, Ti<0.15 others <0.05, remainder aluminium. In an embodiment the method comprises naturally aging the product forming in at least one process, such as stretch forming, drawing, flow spinning, and/or bending and artificial aging at a temperature from 280 to 340° F. (138 to 171° C.) for a duration from 6 to 36 hours. The method is particularly useful to make armor products.
