How the printed metal performs
Printed-property minimums from the CNPC Powder catalog (Ve.2609). A guide for your own qualification, not design data.
| Condition | Orientation | Yield, MPa | UTS, MPa | Elongation | Rel. density | Hardness, HV1 |
|---|---|---|---|---|---|---|

Heat treatment
Manufacturer data
- Heat treatment in the catalog data: 350 °C for 8 hours, which raises tensile strength to at least 539 MPa, thermal conductivity from 83 to 116 W/(m·K) and electrical conductivity from 19.0 to 25.0 %IACS.
- Scalmalloy® is a registered trademark of APWORKS GmbH (Airbus Group), used by CNPC Powder under license.
Before you order
Aluminum powder is reactive. A dust cloud of fine aluminum can ignite. Keep it dry, use grounded equipment and an ATEX-rated vacuum, and follow the safety data sheet.
How this Scalmalloy® compares
Published tensile data, X–Y direction unless noted, one representative condition per alloy. Conditions differ, so use this to shortlist, not to design.
| Alloy | Condition | Yield, MPa | UTS, MPa | Elongation | Choose it for | 10 kg |
|---|---|---|---|---|---|---|
| Scalmalloy® | 350 °C, 8 h (CNPC catalog) | ≥ 509 | ≥ 539 | ≥ 8% | Lower price per kg | $2,520 |
| AlSi10Mg | After heat treatment | 182 | 284 | 19% | Lowest weight; good thermal properties | $815 |
| Ti-6Al-4V Grade 23 | 800 °C, 2 h, vacuum (Z, Amaero) | 1054 | 1119 | 13.5% | Highest strength-to-weight; ELI chemistry | $2,405 |
