7475 Aluminum T761
Verifiedmetal7475 Aluminum T761 is a high-strength aluminum-zinc-magnesium-copper alloy in a stretched temper condition providing excellent fracture toughness and stress-corrosion cracking resistance for critical aerospace structural applications. The T761 temper achieves superior damage tolerance through controlled overaging after solution treatment and controlled stretching, making it suitable for highly loaded aircraft components requiring reliable performance in sustained-stress environments.

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.
