Aluminum Square Bar

The advantages of aluminum alloy are lightweight, excellent electrical and thermal conductivity, high corrosion resistance and ductility.

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 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 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.
