7249 Aluminum T7452
Verifiedmetal7249 is a high-strength aluminum-copper-magnesium-zinc alloy designed for aircraft structural applications requiring superior fatigue resistance and damage tolerance; the T7452 temper (solution heat-treated, artificially aged, and stress-relieved by stretching) provides optimized toughness and reduced residual stress in hand-forged components while maintaining yield strengths exceeding 400 MPa and excellent bearing load capability.

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.
