T351
T451 | Solution heat-treated, de-tension treated through stretching of stated burr (remaining deformation 0,5% to 3% for al-sheet under 6 millimetres, 1,5% to 3% for al-sheet 6 millimetres and more, 1% to 3% for rolled or cold drawn bar. 1% to 5% for free or ring forging and rolled ring) and naturally aged. The product contains no further bias after stretching. |
T3510
T4510 | Solution heat-treated, de-tension treated through stretching of stated burr (remaining deformation 0,5% to 3% for extruded bars, profiles and tubes, 0,5% to 3% for drawn tubes) and naturally aged. The product contains no further bias after stretching. |
| T4 | Solution heat-treated and naturally aged. |
| T5 | Cooled from warm working and thereafter artificially aged. |
| T6 | Solution heat-treated and artificially aged. |
| T651 | Solution heat-treated, de-tension treated through stretching of stated burr (remaining deformation 0,5% to 3% for al-sheet under 6 millimetres, 1,5% to 3% for al-sheet 6 millimetres and more, 1% to 3% for rolled or cold drawn bar. 1% to 5% for free or ring forging and rolled ring) and artificially aged. The product contains no further bias after stretching. |
| T6510 | Solution heat-treated, de-tension treated through stretching of stated burr (remaining deformation 1% to 3% for extruded bars, profiles and tubes, 0,5% to 3% for drawn tubes) and artificially aged. The product contains no further bias or stretching. |
| T7 | Solution heat-treated and over-aged. |
| T73 | Solution heat-treated and over-aged to give the best tension-resistance against corrosion. |
