Temper Definition
O Annealed
H112 Slightly strain harden from working at an elevated temperature or from limited amount of cold work
T3 Solution heat-treated, cold worked and naturally aged
T5 Cooled from an elevated temperature shaping process and then artificially aged
T6 Solution heat-treated 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)
T651 Solution heat-treated, stress-relieved by stretching a controlled amount (permanent set 1% to 3% for rolled or cold-finished rod and bar) and then artificially aged
T3511 Solution heat-treated and stress-relieved by stretching to produce a normal permanent set of 1-1.5%, but not less than 1% nor more than 3%
T6511 Solution heat-treated, stress-relieved by stretching and artificially aged with minor straightening
