Mechanical-Property Data CT 91-T7E69 Aluminum, Powder Metallurgy Product

摘要

CT 91-T7E69 aluminum alloy is a powder metallurgy product of Alcoa. The material was received as two 1-1/2-inch thick x 4-1/2-inch wide x 4-foot lengths. The CT 91 aluminum was received in the T7E69 condition. This temper was designed to have good static strength and fatigue resistance. Results of these tests show higher tensile, shear, and fatigue data as compared to the T7E70 temper while giving lower fracture toughness values.
