2024 Aluminum T351 is a solution heat-treated and stress-relieved aluminum-copper alloy (nominally 4.4% Cu, 1.5% Mg, 0.6% Mn) used in high-strength aerospace and defense structures. The T351 temper provides excellent fatigue resistance and fracture toughness through controlled stress relief, making it the preferred condition for aircraft wing skins, fuselage components, and highly stressed fasteners operating in service environments.
