7475 aluminum is a high-strength Al-Zn-Mg-Cu alloy designed for critical aerospace structural applications requiring superior fatigue resistance and stress-corrosion cracking resistance compared to 7075. This alloy operates effectively up to ~150°C and is specified for highly stressed aircraft fuselage and wing components where damage tolerance and long-term durability in service are paramount.
