7249 Aluminum T7451 is a high-strength Al-Zn-Mg-Cu alloy in a overaged condition (T7451) that provides improved stress-corrosion cracking (SCC) resistance compared to T73, while maintaining tensile strength suitable for aerospace structural applications. The T7451 temper delivers controlled yield strength with enhanced resistance to sustained-load cracking in marine and high-humidity environments, making it suitable for critical aircraft components where both strength and corrosion durability are required.
