Alloy and cast alloy product ideally suited for use as a component, for example, in a vehicle frame or subframe, i.e., a body-in-white, comprising an alloy comprising about 0.15 to .35 wt.% magnesium, and about 8.50 to 11.00 wt.% sillicon, and about 0.40 to 0.80 wt.% manganese, and, with preferably less than 0.50 wt.% iron, the balance substantially aluminum and incidental elements and impurities, such as strontium, sodium, and antimony for modification of the silicon morphology. The alloy is typically solidified into ingot derived working stock by continuous casting or semin-continuous casting into a shape suitable for remelt for casting, which shape is typically an ingot billet. This alloy demonstrates reduced die erosion, notwithstanding its low iron content. |
