Aluminum Round Bar

Aluminum Round Bar is most commonly produced through the process of extrusion or cold drawing. By those processes, aluminum bar is manufactured by pushing or drawing the material (round billet or bar stock) through a die with the desired dimension that is under pressure. And these processes elongate the aluminum billet into round shape pieces that can be machined into all kinds of applications by further fabrications.

Temper Definition
O Annealed
H112 Slightly strain harden from working at an elevated temperature or from limited amount of cold work
T4 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
