ABSTRACT:
A wrought article possessing a fine recrystallized grain size which is prepared from an aluminum base alloy comprising, in weight percent, up to .6% silicon, up to .7% iron, up 1.5% manganese and 0.03 - 0.20% vanadium. The alloy may be cast by the DC casting method and does not require a homogenizing treatment. The alloy may be hot and cold worked, and retains its fine grain through annealing without requiring a high rate of heating to annealing temperature.
