7175 Aluminum T66
Verifiedmetal7175 aluminum alloy (Zn-Mg-Cu system) in T66 temper is a high-strength aerospace alloy combining solution heat treatment, controlled stretching, and artificial aging to achieve maximum yield strength with improved stress-corrosion cracking resistance compared to T73 variants. Primary applications include aircraft structural components and highly stressed forgings requiring tensile strengths exceeding 500 MPa with enhanced resistance to sustained-load cracking in marine and humid environments.

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.
