· 7049 Aluminum Alloy

7049/7149 aluminum is a high-strength Al-Zn-Mg-Cu alloy used in aircraft structural applications, offering tensile yield strengths of 70–80 ksi in peak-aged conditions with good fatigue resistance and fracture toughness. Available tempers range from peak-strength T6 variants (T6151, T61511) to overaged T7 conditions (T73–T77511) that trade some strength for improved stress-corrosion cracking resistance and damage tolerance at elevated temperatures.

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.
