7475 Aluminum T7451

metal

7475 aluminum T7451 is a high-strength Al-Zn-Mg-Cu alloy subjected to solution heat treatment, controlled stretching, and overaging, delivering enhanced stress-corrosion cracking (SCC) resistance and fracture toughness with minimal loss in yield strength compared to T651. Primary applications include critical aerospace structures, pressure vessels, and military aircraft components where SCC susceptibility must be minimized without sacrificing damage tolerance.

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.
