7249 Aluminum

Verifiedmetal

7249 is an Al-Zn-Mg-Cu alloy in the 7xxx series designed for high-strength aerospace applications requiring excellent fatigue resistance and stress-corrosion cracking (SCC) resistance; it combines strength levels comparable to 7075 with improved SCC resistance through controlled grain structure and overaging tempers (T74xx, T75xx, T77xx variants).

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.
