Abstract
Aluminum alloy products particularly for use in automotive applications may be advantageously produced from a body of aluminum base alloy consisting essentially of, by weight, 0.4 to 1.2% Si, 0.4 to 1.1% Mg, 0.2 to 0.8% Mn, 0.05 to 0.35% Fe, 0.1 to 0.6% Cu, the balance essentially aluminum and incidental elements and impurities. The alloy body may be homogenized at a temperature in the range of 900.degree. to 1100.degree. F and thereafter worked into wrought products such as sheet or extrusions which are solution heat treated and quenched and aged to a T4 condition prior to forming into automotive body panels, bumpers or the like, which may then be strengthened by heating or aging to the T6 condition.
