Brand: MatWorld

metal

7475 Aluminum T7751 is a zinc-aluminum-magnesium-copper alloy in the overaged T7751 temper, providing tensile strengths of 435–470 MPa with improved stress-corrosion cracking (SCC) resistance through controlled precipitation. This condition is used in aircraft fuselage skins and fastener applications where resistance to sustained tensile stress in saltwater environments is critical, sacrificing some peak strength for enhanced fracture toughness and corrosion durability.

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.
