    摘要: An A-rated, aluminum alloy suitable for machining, said alloy consisting essentially of: about 4-5.75 wt. % copper, about 0.2-0.9 wt. % bismuth, about 0.12-1.0 wt. % tin, the ratio of bismuth to tin ranging from about 0.8:1 to 5:1, up to about 0.7 wt. % iron, up to about 0.4 wt. % silicon, up to about 0.3 wt. % zinc, the balance aluminum, incidental elements and impurities. On a preferred basis, this alloy contains about 4.4-5.0 wt. % copper, about 0.4-0.75 wt. % bismuth, about 0.2-0.5 wt. % tin, the ratio of bismuth to tin ranging from about 1:1 to 3:1, about 0.2 wt. % or less iron and about 0.2 wt. % or less silicon. The alloy is substantially lead-free, cadmium-free and thallium-free. There is further disclosed an improved method for making screw machine stock or wire, rod and bar product from this alloy by casting, preheating, extruding, solution heat treating, cold finishing and aging the same.

    摘要: An A-rated aluminum alloy suitable for machining, said alloy consisting essentially of: about 0.15-1.0 wt. % copper, about 1.01-1.5 wt. % tin, about 0.65-1.35 wt. % magnesium, about 0.4-1.1 wt. % silicon, about 0.00 2-0.35 wt. % manganese, up to about 0.5 wt. % iron, up to about 0.15 wt. % chromium and up to about 0.15 wt. % titanium, the remainder substantially aluminum. On a preferred basis, this alloy contains about 0.51-0.75 wt. % copper, about 1.1-1.3 wt. % tin, about 0.7-0.9 wt. % magnesium and about 0.45-0.75 wt. % silicon. The alloy is substantially free of lead, bismuth, nickel, zirconium and cadmium. There is further disclosed an improved method for making screw machine stock or wire, rod and bar product from this alloy by casting, preheating, extruding, solution heat treating, cold finishing and thermally processing the aforementioned alloy composition.
