Conditions and tempers
How 6063 is supplied and what each state is for. The default is what FabDigit quotes unless your drawing says otherwise.
| Condition | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness |
|---|---|---|---|---|---|
T4 Solution heat treated, naturally aged (T4) | Medium strength, still bendable — parts formed after machining, rivets | 90 | 172 | 22 | 46 HB |
T6 Solution heat treated, artificially aged (T6) | Heavy load-bearing frames, high-stress parts, precision components | 214 | 241 | 12 | 73 HB |
T5 Cooled from hot working, artificially aged (T5) | Moderate-stress extrusions — trims, frames, architectural profiles | 145 | 186 | 12 | 60 HB |
T52 Stress relieved by compression, aged (T52) | Like T51 with compression stress relief — stable light-duty shapes | 110 | 152 | 12 | 50 HB |
Heat treatment and post-processing
Operations FabDigit's suppliers routinely run on 6063, ranked by how often they make sense for this grade.
Heat treatment
| Age T6 (Aluminum) | Solution + artificial age to peak strength |
|---|---|
| Age T651 (Aluminum) | T6 + stress relief stretch (plate) |
| Full Anneal | Restore ductility; relieve residual stress; coarsen grain |
| Stress Relief | Reduce residual stress without changing structure |
| Age T73 (Aluminum) | Over-age 7000 for SCC resistance |
