2024 Aluminum T351X is a copper-aluminum alloy in an artificially aged condition following solution heat treatment and stress relief stretching, providing high strength-to-weight ratio (ultimate tensile strength ~70 ksi) with improved stress-corrosion cracking resistance compared to T4 temper. Primary applications include aircraft fuselage skin, wing components, and fasteners requiring sustained strength at elevated temperatures up to ~300°F with controlled residual stress levels.
