Aluminum Flat Bar

Aluminum Flat Bar (rectangular bar) is most commonly produced through the process of extrusion or cold drawing. By this process, aluminum flat bar is manufactured by pushing the material (round billet or bar stock) through a die that is under pressure. These processes elongate the aluminum billet into a desired flat shape. Flat bar is likely used in metalworking or forging operations where it will be shaped into something usable. Flat bar can also be cut from thick plates upon request.

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
