7049/7149 Aluminum T73511
Verifiedmetal7049/7149 aluminum T73511 is a high-strength Al-Zn-Mg-Cu alloy in a stress-relieved and artificially aged condition, designed for aerospace structural applications requiring excellent damage tolerance and stress-corrosion cracking (SCC) resistance. The T73511 temper provides reduced yield strength compared to T73 conditions but significantly improved resistance to SCC and exfoliation corrosion, making it suitable for critical airframe components in aircraft wings and fuselages.

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.
