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 recrystallization. During formation of the alloys, homogenization, solution heat treating and artificial aging processes are preferably employed.

摘要： The present invention is a process to use aluminum alloy scrap to manufacture high quality machinable tooling plate. This is an new use for this scrap which has heretofore been used in lower quality products. The tooling plate thus made has superior properties when machined as it produces smaller chips and/or a limited of spirals from the plate. Large chips and long spirals create problems and a smaller chip greatly facilitates the machining operation.
