... properties in combination with excellent castability and saltwater corrosion resistance. The excellent corrosion resistance of high-purity AZ91D is essentially the result of controlling the impurity level of three critical contaminants: iron, nickel, and copper. High-purity AZ91D alloy has replaced less-pure...
