7475 Aluminum T77511 is a high-strength aluminum-zinc-magnesium-copper alloy in a highly-worked temper condition, providing tensile strengths typically in the 500–580 MPa range with improved stress-corrosion cracking (SCC) resistance compared to T73 tempers through controlled overaging. Applications include aircraft structural components, landing gear, and fasteners requiring optimal combinations of strength, fatigue resistance, and fracture toughness in sustained-load environments.
