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 5-12 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.
