7249 Aluminum T77511
metal7249 aluminum alloy is a zinc-primary precipitation-hardened alloy designed for high-strength aerospace applications requiring excellent fracture toughness and stress-corrosion cracking resistance. The T77511 temper (solution heat-treated, stretched, and artificially aged) provides yield strengths of 415–450 MPa with enhanced toughness and dimensional stability, suitable for critical aircraft structural components operating in high-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.
