    摘要: An aluminum base alloy wrought product having improved corrosion resistance in addition to combinations of strength and toughness. The product comprises 0.2 to 5.0 wt. % Li, 0.05 to 6.0 wt. % Mg, at least 2.45 wt. % Cu, 0.05 to 0.16 wt. % Zr, 0.05 to 12 wt. % Zn, 0.5 wt. % max. Fe, 0.5 wt. % max. Si, the balance aluminum and incidental impurities and has the ability to develop improved combinations of strength and toughness in response to an aging treatment. Prior to an aging step, the product having imparted thereto a working effect equivalent to stretching so that after an aging step it has improved combinations of strength and toughness.
