7475 Aluminum T651
VerifiedmetalUNS A97475
7475 aluminum is a zinc-copper-magnesium precipitation-hardened alloy engineered for high-strength aerospace structural applications, particularly where exfoliation corrosion resistance is critical; T651 temper (solution heat-treated, artificially aged, and stress-relieved by controlled stretching) provides ultimate tensile strengths in the 470–510 MPa range with improved through-thickness properties and corrosion resistance compared to T73 variants, making it suitable for highly loaded aircraft components including wing skins, fuselage frames, and pressure vessels.

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.
