    • Aluminum alloy products about 4 inches thick or less that possesses the ability to achieve, when solution heat treated, quenched, and artificially aged, and in parts made from the products, an improved combination of strength, fracture toughness and corrosion resistance, the alloy consisting essentially of: about 6.8 to about 8.5 wt. % Zn, about 1.5 to about 2.00 wt. % Mg, about 1.75 to about 2.3 wt. % Cu; about 0.05 to about 0.3 wt. % Zr, less than about 0.1 wt. % Mn, less than about 0.05 wt. % Cr, the balance Al, incidental elements and impurities and a method for making same. The invention alloy is useful in making structural members for commercial airplanes including, but not limited to, upper wing skins and stringers, spar caps, spar webs and ribs of either built-up or integral construction. The invention alloy may be aged by 2 or 3 step practices while exceeding the SCC requirements for applications for which the invention alloy is primarily intended. The flexibility of the invention in this regard is useful for its application in multi-alloy or multi-material systems joined by welding or bonding and subsequently aged.
    • 约4英寸厚或以下的铝合金产品具有在固溶热处理,淬火和人工老化的同时实现的能力,以及由产品制成的零件中,改进了强度,断裂韧性和耐腐蚀性的组合,该合金组成 基本上为:约6.8至约8.5wt。 %Zn,约1.5至约2.00wt。 %Mg,约1.75至约2.3wt。 %Cu; 约0.05至约0.3wt。 %Zr,小于约0.1wt。 %Mn,小于约0.05wt。 %Cr,余量为Al,附带元素和杂质及其制备方法。 本发明合金可用于制造商用飞机的结构构件,包括但不限于上部翼皮和桁条,翼梁盖,翼梁腹板和构成或整体结构的肋。 本发明合金可以通过2或3步骤的方式老化,同时超过本发明合金主要用途的应用的SCC要求。 在这方面,本发明的灵活性对于其在通过焊接或粘合并随后老化而连接的多合金或多材料体系中的应用是有用的。
