Abstract
A process for forming cast, magnesium based alloy articles having reduced microshrinkage comprising the steps of forming a molten alloy consisting essentially of magnesium together with 4 to 10% by weight aluminum, 0 to 1% by weight manganese, and either 0 to 3% by weight zinc or 0 to 1% by weight silicon, adding to the molten alloy 0.01 to 2% by weight strontium, and molding the molten alloy and solidifying to form a cast alloy article.
