Aluminum alloy is soft and usually alloyed with copper, zinc, magnesium, silicon, manganese and lithium to increase strength. When aluminum alloy is exposed to air, an anti-oxidant coating will be formed instantly to protect products. Aluminum alloy is one of the lightest metals. The application of products ranges from precision technology to daily commodities.

| 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. |
