Temper Definition
O Annealed
H14 Strain Hardened, 1/2 Hard
H112 Slightly strain harden from working at an elevated temperature or from limited amount of cold work
T4 Solution heat-treated and naturally aged
T5 Cooled from an elevated temperature shaping process and then artificially aged
T6 Solution heat-treated and then artificially aged
T651 Solution heat-treated, stress-relieved by stretching a controlled amount and then artificially aged
T66 Solution heat-treated and then artificially aged - mechanical property level higher than T6 achieved through special control of the process (6000 series alloys)
T6511 Solution heated-treaded, stress-relieved by stretching a controlled amount and then artificially aged. Minor straightening is allowed after stretching to comply with standard tolerances
