2026 aluminum is a Cu-Mg-Ni precipitation-hardenable alloy used in aerospace airframe structures requiring high strength-to-weight ratio and damage tolerance. T3511 temper (solution heat-treated, cold-worked, and stress-relieved) provides controlled strength and reduced residual stress suitable for extrusions in aircraft fuselage and wing components, with excellent bearing strength and fatigue resistance in moderately elevated temperature applications up to ~150°C.
