2014 aluminum (T651X) is a copper-alloyed wrought aluminum alloy in an artificial age-hardened condition with controlled stretching, providing high strength (ultimate tensile strength ~70 ksi / 485 MPa) and improved stress-relief characteristics suitable for aerospace structural applications. The T651X temper delivers enhanced fracture toughness and reduced quench sensitivity compared to unstretched T651, making it preferred for thick-section forgings and extrusions in critical load-bearing components where damage tolerance is required.
