# 7075 Aluminum T7451 7075 is a high-strength aluminum-zinc-magnesium-copper alloy used primarily in aerospace structures where maximum strength-to-weight ratio is critical. T7451 is an overaged temper (solution heat-treated, stress-relieved, and artificially aged) that trades some peak hardness for improved stress-corrosion cracking (SCC) resistance and dimensional stability, making it suitable for thick-section applications and components subject to sustained tensile stress.
