7049/7149 Aluminum T7651

metal

7049/7149 Aluminum T7651 is a high-strength Al-Zn-Mg-Cu alloy in overaged temper condition, providing reduced susceptibility to stress-corrosion cracking while maintaining tensile strength in the 470–510 MPa range; primary use is in aircraft structural components and landing gear where combined strength, damage tolerance, and SCC resistance are critical.

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.
