HIGH STRENGTH ALUMINUM CASTING ALLOYS
Abstract
The results of tensile tests on three types of high-purity cast aluminum alloys are presented. Alloy A (zinc-magnesium-chromium type), when heat treated in 3-inch casting thickness, exhibits approximately 48,000 psi. yield strength, 55,000 psi. tensile strength, and 8% elongation. These minimum values are also observed 5-1/2 inches from a chilled end of a heat treated, 1-inch thick, cast plate. C355 alloy (silicon-copper magnesium type) ranks second in yield and tensile strengths, attaining 80 to 85% of the Alloy A strength levels. Alloy A356 (silicon-magnesium type) ranked third.
