6061-T651 is a medium-strength Al-Mg-Si alloy in a solution heat-treated and stress-relieved condition, widely used in aerospace structural applications, marine hardware, and general engineering components where moderate strength and excellent corrosion resistance are required. This temper provides controlled mechanical properties suitable for precision machining with residual stress relief to minimize distortion in service.
