Aluminum base alloys containing 0.5 to 1.3% silicon, 0.8 to 1.8% copper, 0.1 to 0.4% manganese, 0.4 to 1.0% magnesium, up to 0.6% iron, 0.20% chromium, 0.5% zinc, 0.15% titanium and 0.05% each of other components up to 0.15% total, the balance aluminum are described. Such alloys demonstrate optimum strength, formability and corrosion resistance properties for use as autobody sheet alloys.
