7475 Aluminum T61
Verifiedmetal7475 Aluminum T61 is a high-strength aluminum-zinc-magnesium-copper alloy in an artificially aged condition, providing ultimate tensile strengths in the 500+ MPa range with improved stress-corrosion cracking resistance compared to 7075. Used primarily in aerospace airframe structures and military applications where damage tolerance, fatigue performance, and bearing strength are critical, available as sheet per AMS 4084 specification.

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.
