Alloy and cast alloy product ideally suited for use as a component in a vehicle frame or subframe, i.e., body-in-white, comprising an alloy consisting of about 2.5 to 6.5 wt.% magnesium, less than approximately 0.5 wt.% silicon, approximately 0.5 to 1.4 wt.% manganese, less than approximately 0.5wt.% iron, less than approximately 0.15 wt.% titanium, the balance substantially aluminum and incidental elements and impurities. The aluminum/magnesium alloy is typically solidified into ingot derived working stock by continuous casting or semi-continuous cashing into a shape suitable for remelt for casting, which shape is typically an ingot billet. Excellent mechanical properties are obtained from a cast product that is not subjected to heat treating operations subsequent to casting. |
