ABSTRACT:
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 2.00 to 5.00 wt. % magnesium, up to approximately 0.30 wt. % silicon, approximately 0.20 to 1.60 wt. % manganese, up to approximately 1.00 wt. % iron, and between about 0.10 to 0.30 wt. %, zirconium, 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 casting 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 high temperature heat treating operations subsequent to casting.
