Alloys and Treatments
The alloys used by EXTRUAL for the manufacturing of the sections are adapted to meet the client requirements and the functionality planned for the final product. In this way, the most common are the following:
| ALLOY | APPLICATION |
|---|---|
| 6060 | Architectonics |
| 6063 | Architectonics |
| 6463 | Decoration (high gloss) |
| 6106 | Semi-structural |
| 6005 A | Structural |
| 6082 | Structural |
At the same time, the heat treatments applied to the sections vary depending on the mechanical characteristics to be achieved:
| TREATMENT | CHARACTERISTICS | |
|---|---|---|
| T4 | Press exit forced cooling and artificial ageing | Low mechanical characteristics |
| T5 | Press exit cooling and artificial ageing | Normal mechanical characteristics |
| T6 | Press exit forced cooling and natural ageing | High mechanical characteristics |
| Intermediate between T4 and T5 | Special characteristics (p.g.: Section forming) |
