7049/7149 Aluminum T61511

metal

7049/7149 Aluminum T61511 is a high-strength Al-Zn-Mg-Cu alloy in a premium temper condition (solution heat-treated, artificially aged, and stress-relieved by stretching) that delivers exceptional fatigue resistance and fracture toughness for primary aircraft structures. This temper is used extensively in fighter aircraft and military transport applications where sustained cyclic loading, damage tolerance, and corrosion resistance are critical performance requirements.

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.
