Product detail:
Aluminum Alloy Round Bar & Billet
Given its own softness, it is usually alloyed together with copper, zinc, magnesium, silicon, manganese and lithium to improve its strength. As soon as it is exposed to air, the aluminum alloy instantly generates an antioxidant layer to protect the products. This type of material can be considered as one of the metals that weigh the least, for this very reason it covers very extensive applications, from high precision technology to daily uses.

| H112 | Applied to semi-products that can acquire some strain hardening at high temperature and for which there are limits of mechanical characteristics |
| T3 | Solution heat treatment, quenching, pungency and natural aging |
| T3511 | Applied to semi-products that after the solution and tempering heat treatment, indicates the acrimony they receive from a last straightening by controlled traction from 1% to 3. Natural maturation. |
| T4 | Solution heat treatment, quenching, and natural maturation |
| T5 | Quenching heat treatment from extrusion temperature and artificial maturation |
| T6 T651 | Solution treatment, quenching and artificial maturation Solution heat-treated, stress relived by stretching a controlled amount (permanent set 1% to 3% for rolled or cold-finished rod and bar) and then artificially aged |
| T66 | Solution heat treatment, quenching and artificial maturation, with a level of mechanical properties higher than that of T6 through a special control process of the 6000 series alloy. |
| T6511 | Applied to semi-products that after the solution and tempering heat treatment, indicates the acrimony they receive from a last straightening by controlled traction from 1% to 3. Also applied to bars, profiles, extruded and stretched tubes: percentage of Controlled tensile straightened acrimony of 3%, minus tube 0.5% to 3%. Artificial ripening. |
