<p>An aluminum alloy containing the following elements in the stated amounts: 0.6 ≤Mg ≤ 0.9; 0.25 ≤Si ≤ 0.6; 0.25 ≤Cu ≤ 0.9; Fe ≤ 0.4; Mn ≤ 0.4; the total of the amounts of Cu, Si and Mg being, in atomic weight percent, more than 1.2 % and less than 1.8 %. These alloys may be subjected to homogenization at about 470 to 560 °C for more than four hours, hot rolling at a temperature in the range of 400 to 580 °C, cold rolling, solutionizing at a temperature in the range of 470 to 580 °C, and natural aging at ambient temperature. The alloys may then be used as structural components for all aluminum vehicles and may be recycled with other aluminum alloys used in such vehicles.</p> |
