    摘要： A 2000 series aluminum alloy characterized by high strength, high fatigue resistance, and high fracture toughness consists essentially of 4.2 to 4.7 percent copper, 1.3 to 1.8 percent magnesium, 0.8 to 1.3 percent manganese, 0.08 to 0.15 percent zirconium, maximums of 0.15 percent iron, 0.12 percent silicon, 0.25 percent zinc, 0.15 percent titanium, 0.10 percent chromium, 0.05 percent of each of any other trace elements present, and a maximum total of such other trace elements of 0.15 percent, the balance of the alloy being aluminum. The foregoing alloy is hot-worked and heat-treated to yield a final wrought product having a highly elongated and substantially unrecrystallized microstructure.

    摘要： A 2000 series aluminum alloy characterized by high strength, very high fatigue resistance, and very high fracture toughness consists essentially of3.8%to 4.4 % copper, 1.2%to 1.8% magnesium, 0.3% to 0.9% manganese, maximums of 0.12% silicon, 0.15% iron, 0.25% zinc, 0.15 % titanium, 0.10% chromium, 0.05%of each of any othertrace elements present, and a maximum total of such other trace elements of 0.15%, the balance of the alloy being aluminum. It is preferred, especially for plate products, that the maximum iron and silicon levels be restricted to 0.12% and 0.10%, respectively. For extruded products, the foregoing alloy is hot worked to yield a wrought product having a substantially unrecrystallized structure. For plate products, the alloy is subjected to room temperature preaging and a cold rolling treatment to provide a reduction in gauge of from 9% to 13%.
