7475 Aluminum T61 is a high-strength aluminum-zinc-magnesium-copper alloy in an artificially aged condition, providing ultimate tensile strengths in the 500+ MPa range with improved stress-corrosion cracking resistance compared to 7075. Used primarily in aerospace airframe structures and military applications where damage tolerance, fatigue performance, and bearing strength are critical, available as sheet per AMS 4084 specification.
