7075 Aluminum T6 is a high-strength aluminum-zinc alloy (with magnesium and copper) solution heat-treated and artificially aged to peak hardness, providing tensile strengths in the 70–80 ksi range with excellent bearing strength and rigidity for critical aerospace structural applications requiring high strength-to-weight ratios. The T6 temper delivers superior fatigue and bearing properties compared to other 7075 conditions but exhibits lower fracture toughness and stress-corrosion resistance, limiting use to applications where sustained tensile stress and corrosive environments are not simultaneously severe.
