7475 aluminum is a zinc-copper-magnesium Al-Zn-Cu-Mg alloy used in high-strength aerospace applications requiring excellent damage tolerance and fatigue resistance. The T7651 temper (solution heat-treated, stress-relieved, and overaged) provides yield strength in the 350–420 MPa range with improved stress-corrosion cracking resistance compared to T6 conditions, making it suitable for critical structural components in aircraft wings and fuselages.
