An aluminum alloy containing the following elements in the stated amounts:
0.6.ltoreq.Mg.ltoreq.0.9; 0.25.ltoreq.Si.ltoreq.0.6;
0.25.ltoreq.Cu.ltoreq.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.degree. C. for more than four hours, hot rolling at a temperature in
the range of 400 to 580.degree. C., cold rolling, solutionizing at a
temperature in the range of 470 to 580.degree. 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.
