Abstract
A weldable aluminum base alloy product is disclosed which is characterized by high strength, including high resistance to ballistic penetration and resistance to stress-corrosion cracking. The alloy consists essentially of from above 5 wt. % to 7 wt. % copper, 0 to 0.8 wt. % manganese, 0.1 wt. % titanium, 0 to 0.25 wt. % vanadium, 0 to 0.25 wt. % zirconium and 0.10 to 0.30 wt. % magnesium with the balance consisting essentially of aluminum. The alloy is cold worked a minimum amount equivalent to 6% stretching at room temperature after solution heat treatment and quenching, preferably by stretching. The alloy is then aged, after cold working, for at least 2 hours at a temperature of at least 121.degree. C. (250.degree. F.).
