摘要
This relates to an aluminum alloy product, in particular an age-hardenable Al—Zn—Mg type alloy product for structural members, the alloy product combining a high strength with high toughness and reduced quench sensitivity, and having a chemical composition including, in wt. %: Zn about 3 to 11%, Mg about 1 to 3%, Cu about 0.9 to 3%, Ge about 0.03 to 0.4%, Si max. 0.5%, Fe max. 0.5%, balance aluminum and normal and/or inevitable elements and impurities. Furthermore, this relates to a method of producing such aluminum alloy products.
