Abstract
This invention relates to a method and a stable alloy of zinc, the alloy having tensile strength in excess of 65,000 psi and a mechanical stability greater than 15 percent, the stable alloy being formed by homogenizing an alloy containing from about 20 to 28 weight percent aluminum, from about 0.1 to 3.5 percent copper, about 0.01 to about 0.5 percent magnesium, and the remainder zinc, at a temperature between about 550.degree. F., to 750.degree. F., to effect homogenization of the alloy, cooling the homogenized alloy to a rolling temperature of about 350.degree. F., at a rate of about 10 to 50.degree. F., per minute and thereafter rolling the homogenized alloy at a temperature below 350.degree. F., to attain between 10 and 70 percent reduction thereof.
