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.
Specifications, equivalent names and how AlSi10Mg compares

Equivalent names on LPBF machines
“Similar materials” in the datasheet; for parameter selection only, not machine-maker approvals
The datasheet for this alloy does not list equivalent names. Ask our materials engineer which machine profiles teams start from.
How it compares
Published tensile data, X–Y direction unless noted, one representative condition per alloy. Conditions differ, so use this to shortlist, not to design.
