7075-T6151 is a high-strength aluminum-zinc alloy (with copper and magnesium) solution heat-treated and artificially aged with controlled stretching, delivering tensile strength of 505–530 MPa and improved fracture toughness and stress-corrosion cracking (SCC) resistance compared to T6, suited for critical aerospace and defense structural applications subject to sustained tensile loading. The T6151 condition is specified for components where the controlled residual compressive stress from stretching is beneficial for fatigue life and crack propagation resistance.
