Description
The advantage properties of aluminum alloy have light weight, excellent electrical and thermal conductivity, highly corrosion resistant and ductility.
Aluminum alloy is soft and are usually alloyed with copper, zinc, magnesium, silicon, manganese and lithium to increase strength. Aluminum alloy is exposed to air that instantly forms an anti-oxidant coating to protect products. Aluminum alloy is one of the lightest metals, the application of products ranges from precision technology to daily commodities.

Temper designation (For Reference)
| 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 |
| T3511 | Solution heat-treated, stress relived by stretching a controlled amount (permanent set 1% to 3% for extruded rod, bar, shapes and tube, 0.5% to 3% for drawn tube) and naturally aged |
| T4 | Solution heat-treated and naturally aged |
| T5 | Cooled from an elevated temperature shaping process and then artificially aged |
| T6 T651 |
Solution heat-treated and then artificially aged Solution heat-treated, stress relived by stretching a controlled amount (permanent set 1% to 3% for rolled or cold-finished rod and bar) 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 (permanent set 1% to 3% for extruded rod, bar, shapes and tube, 0.5% to 3% for drawn tube) and then artificially aged. Minor straightening is allowed after stretching to comply with standard tolerances |
