7175 Aluminum T7451

metal

7175 Aluminum T7451 is a high-strength Al-Zn-Mg-Cu alloy in an over-aged temper condition that provides reduced susceptibility to stress-corrosion cracking while maintaining tensile strength typically 70–75 ksi yield and 80–85 ksi ultimate in thin sheet. This temper is used in aerospace pressure vessels, wing skins, and fuselage components where sustained loads, environmental exposure, and resistance to stress-corrosion cracking in the short-transverse direction are critical design drivers.

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.
