7175 aluminum T73511 is a high-strength zinc-copper-magnesium alloy in an overaged temper condition that provides enhanced stress-corrosion cracking resistance with tensile yield strength around 435 MPa, suitable for aircraft structural components and fasteners requiring superior corrosion performance in humid environments. The T73511 condition (solution heat-treated, cold-worked, and artificially overaged) balances strength retention with improved exfoliation corrosion resistance compared to T6 tempers, making it preferred for long-term durability in aerospace applications per AMS 4344 specification.
