Aluminium Flat Bar
The advantages of aluminium alloy are lightweight, excellent electrical and thermal conductivity, high corrosion resistance and ductility.
Aluminium alloy is soft and usually alloyed with copper, zinc, magnesium, silicon, manganese and lithium to increase strength. When aluminium alloy is exposed to air, an anti-oxidant coating will be formed instantly to protect products. Aluminium 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 |
| 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. |
