| Temper | Definition |
|---|---|
| O | Annealed |
| 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 |
| T66 | Solution heat-treated and then artificially aged - mechanical property level higher than T6 achieved through special control of the process (6000 series alloys) |
| 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 |
