7049/7149 Aluminum T7451

metal

7049/7149 Aluminum T7451 is a high-strength aluminum-zinc-magnesium alloy in overaged condition, providing reduced susceptibility to stress-corrosion cracking while maintaining tensile strength in the 470–510 MPa range, primarily used in aerospace airframe structures and pressure vessels. The T7451 temper achieves stress relief through controlled overaging, making it suitable for critical applications requiring both high strength and enhanced resistance to environmental stress-corrosion cracking in chloride-containing 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.
