Heat treatment and post-processing
Operations FabDigit's suppliers routinely run on AlSi10Mg, 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 |

Property data is compiled from published supplier and standards handbooks and normalised for comparison; hardness values on non-Brinell scales are converted approximately for charting only. Manufacturability limits are FabDigit quote-engine defaults and may be relaxed by engineering review. Nothing on this page is a certification — request mill certs, CoC or material test reports with your order.
