How the printed metal performs
Room-temperature tensile data published by Carpenter Additive for PowderRange AlSi10Mg: average of at least 5 samples per orientation and condition. A guide for your own qualification, not design data. The datasheet does not name the heat-treatment cycle.
| Condition | Orientation | Yield, MPa | UTS, MPa | Elongation | Reduction of area |
|---|---|---|---|---|---|
| After heat treatment | X–Y | 182 | 284 | 19% | 40% |
| Z | 180 | 290 | 15% | 32% |
Heat treatment
Carpenter datasheet, process guidance
- T6 (solution anneal, quench, age) can be used after the build, as for cast parts; follow the cycle your specification calls for.
- Parts can be spark-eroded, welded, micro shot-peened, polished and coated.
- Associated specifications: ASTM F3318, DIN EN 1706, EN AC-43000.
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 and your machine maker’s guidance for aluminum.
Will it run on my printer?
Runs on open-parameter laser powder bed fusion systems. Ask our materials engineer for starting parameters for your machine.
