Abstract
A method for manufacturing an aluminum alloy sheet suitable for high-speed forming includes subjecting the alloy to a homogenization treatment, hot rolling and cold rolling the homogenization treated alloy, thereby obtaining a cold-rolled sheet, and annealing the cold-rolled sheet. The aluminum alloy contains 4.0 to 10.0 wt. % of Mg, 0.2 wt. % of inevitable impurities of Fe and Si, 0.05 wt. % of other impurity elements, and the balance of Al. Another embodiment includes deep drawing the aluminum alloy sheet.
