7075 Aluminum T77511 is a precipitation-hardened aluminum-zinc alloy (with copper and magnesium) in an overaged condition that provides high static strength and improved stress-corrosion cracking (SCC) resistance compared to T73 tempers, with reduced notch sensitivity. This temper is commonly specified in aerospace structures where both damage tolerance and resistance to sustained tensile stress in corrosive environments are critical requirements.
