Aluminum Metapor
Aluminum Metapor is a porous / specialty aluminum — air permeable, porous vacuum mold. Typical values: 30 MPa yield, 2.05 g/cm³, rated to 150 °C. Available for CNC machining at FabDigit.
Properties
Typical room-temperature values for the default supply condition. Metric first, imperial in gray. The bars show where Metapor sits against the other 163 aluminum grades in the catalog.

Heat treatment and post-processing
Operations FabDigit's suppliers routinely run on Metapor, 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.
