Abstract (en)

[origin: WO2013133978A1] New HT aluminum alloy bodies and methods of producing the same are disclosed. The new HT aluminum alloy bodies contain 0.20 - 2.0 wt. % Mg, 0.10 - 1.5 wt. % Si, 0.01 - 1.0 wt. % Fe, and, 0.10 - 1.0 wt. % Cu, wherein, when Si+Cu < 0.60 wt. %, then Fe+Mn <=1.5 wt. %, optionally with up to 1.5 wt. % Mn, optionally with up to 1.5 wt. % Zn, wherein at least one of the Mg, the Si, the Fe, the Cu, the optional Mn, and the optional Zn is the predominate alloying element of the aluminum alloy sheet other than the aluminum, and may be produced by preparing the aluminum alloy body for post-solutionizing cold work, cold working by at least 25%, and then thermally treating. The new HT aluminum alloy bodies may realize improved strength and other properties.
