Abstract: Aluminum alloy products particularly for automotive applications, e.g. panel members, may be produced from a body of aluminum base alloy consisting essentially of, by weight, 0.5 to 0.85% Si, 0.25 to 0.48% Mg, 0.05 to 0.4% Fe, 0.75 to 1.1% Cu, 0.1 to 0.5 wt. % Mn, the balance essentially aluminum and incidental elements and impurities. The alloy body may be homogenized at a temperature in the range 900.degree. to 1100.degree. F. and thereafter worked into a wrought product such as sheet which may be continuously solution heat treated and quenched and aged to a T4 condition prior to forming into vehicular panel members, for example.
