7249 Aluminum T7451
metal7249 Aluminum T7451 is a high-strength Al-Zn-Mg-Cu alloy in a overaged condition (T7451) that provides improved stress-corrosion cracking (SCC) resistance compared to T73, while maintaining tensile strength suitable for aerospace structural applications. The T7451 temper delivers controlled yield strength with enhanced resistance to sustained-load cracking in marine and high-humidity environments, making it suitable for critical aircraft components where both strength and corrosion durability are required.

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.
