7175 Aluminum T77511
metal7175 aluminum T77511 is a high-strength Al-Zn-Mg-Cu alloy in a stabilized temper condition (solution heat-treated, cold-worked, and artificially aged with stress relief) designed for aerospace structural applications requiring sustained elevated temperature performance and stress-corrosion cracking (SCC) resistance. This temper provides tensile yield strength approximately 70–75 ksi with improved toughness and SCC resistance compared to T73 conditions, making it suitable for critical airframe components, fasteners, and pressure vessels in aircraft where long-term thermal and mechanical stability is essential.

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.
