AL T51
T51 is a temper designation applied to aluminum alloys that have been stress-relieved by stretching after heat treatment. Commonly seen in alloys like 6061-T51 and 7075-T51, this temper improves dimensional stability and reduces internal stress, while maintaining good strength and corrosion resistance.
T51 is a temper designation applied to aluminum alloys that have been stress-relieved by stretching immediately after solution heat treatment. This process significantly reduces residual internal stresses, which minimizes distortion during machining and improves dimensional stability in the final product. Commonly used in alloys such as 6061-T51 and 7075-T51, this temper retains the excellent strength, toughness, and corrosion resistance of the base alloys while adding improved reliability for high-precision applications. T51 aluminum alloys are widely used in aerospace, automotive, defense, marine, and industrial engineering sectors where both performance and stability are critical. By combining strong mechanical properties with reduced stress-induced warping, the T51 temper ensures consistent accuracy and durability in complex parts. At GD Prototyping, we provide aluminum alloys in T51 condition to meet the needs of industries that demand high performance, precision, and long-term reliability in both prototypes and large-scale production.
