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 |
|---|---|---|---|---|---|---|
| As-built | — | ≥ 350 | ≥ 420 | ≥ 7% | 99.94% | 127 |
| 250 °C, 2 h | — | ≥ 250 | ≥ 340 | ≥ 10% | — | 100 |
Heat treatment
Manufacturer data
- Heat treatment in the catalog data: 250 °C for 2 hours. It lowers strength but raises thermal conductivity from 103.0 to 181.5 W/(m·K) and electrical conductivity from 23.2 to 43.1 %IACS.
- Use the stress-relief or T6 cycle your specification calls for.
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 AlSi10Mg 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 |
|---|---|---|---|---|---|---|
| AlSi10Mg | 250 °C, 2 h (CNPC catalog) | ≥ 250 | ≥ 340 | ≥ 10% | Lower price per kg | $410 |
| Ti-6Al-4V Grade 23 | 800 °C, 2 h, vacuum (Z, Amaero) | 1054 | 1119 | 13.5% | Highest strength-to-weight; ELI chemistry | $2,405 |
| 316L | As-built | 552 | 703 | 57% | Corrosion resistance; does not age-harden | $670 |
