<p>Disclosed is a method for making an aluminum alloy sheet having controlled levels of strength properties for forming into a container panel. A body of an aluminum alloy consisting essentially of 0.3 to 0.6 wt.% Cu, 1.1 to 1.7 wt.% Mg, 0.3 to 0.6 wt.% Si, 0.3 to 0.55 wt.% Fe, 0.5 to 1.2 wt.% Mn, the remainder aluminum, incidental elements and impurities, is hot rolled to a gauge in the range of 0.12 to 0.16 inch to provide a hot rolled product. The hot rolled product is cold rolled to provide a reduction of 50 to 80% in thickness, then solution heat treated in a range of 850 to 1100 DEG F and rapidly cooled before cold rolling to a final sheet gauge by providing a reduction of 30 to 90% in thickness. <IMAGE></p> |
