7475 Aluminum T61511

metal

7475 Aluminum T61511 is a high-strength Al-Zn-Mg-Cu alloy in a T61511 temper (solution heat-treated, stress-relieved by stretching, and artificially aged) designed for critical aerospace structural applications requiring maximum strength-to-weight ratio and damage tolerance. This temper provides tensile strengths in the 70–80 ksi range with improved stress-corrosion cracking resistance and fracture toughness compared to T6 tempers, making it suitable for highly loaded fuselage skins, wing components, and fastener applications in military and commercial aircraft.

Quality & Standards

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
