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 |
