Clad 7475 aluminum alloy T651 is a zinc-primary aerospace alloy with copper and magnesium additions, clad with pure aluminum for enhanced corrosion resistance, and solution heat-treated plus artificially aged to T651 condition for high strength and controlled stress-relief properties. It provides tensile strengths in the range of 70–80 ksi with good fatigue resistance and fracture toughness suitable for critical airframe components including wing and fuselage skins in high-performance military and commercial aircraft.
