AlSi10Mg Powder
AlSi10Mg Powder Supplier and Exporter
AlSi10Mg powder (EN AC-43000 equivalent) is a nitrogen or argon gas atomised aluminium casting alloy feedstock for additive manufacturing, supplied to ASTM F3318 (PBF) in 15-45 µm, 15-53 µm, 20-63 µm, 45-105 µm, 53-105 µm, 45-150 µm, 53-150 µm size fractions.
The aluminium alloy that actually prints well. Rapid solidification in LPBF produces a much finer structure than casting, so printed properties exceed the cast equivalent.
AlSi10Mg Powder at a Glance
| UNS / designation | EN AC-43000 equivalent |
|---|---|
| Werkstoff (W.Nr.) | 3.2381 |
| Alloy family | Aluminium casting alloy |
| Feedstock specification | ASTM F3318 (PBF) |
| Size fractions | 15-45 µm · 15-53 µm · 20-63 µm · 45-105 µm · 53-105 µm · 45-150 µm · 53-150 µm Held in stock or arranged with the manufacturer, depending on quantity. |
| Production route | Nitrogen or argon gas atomised |
| Density | 2.67 g/cm3 |
| Melting range | 570-590 C |
| Composition | 9-11% silicon with 0.2-0.45% magnesium. The near-eutectic silicon content is what gives it the fluidity and narrow freezing range that suit a melt pool. |
| Minimum order | 5 kg |
| Lead time | 7 days from order confirmation |
| Price | INR 3,400 – 5,000 per kg. Indicative USD 40 – 59 per kg; quoted against grade, form, size and quantity. |
What Properties Does Printed AlSi10Mg Reach?
Printed properties depend on the heat treatment, not just the alloy, so they are given per condition.
| Condition | Tensile strength | Yield strength | Elongation | Hardness |
|---|---|---|---|---|
| As built | 400-460 MPa | 220-280 MPa | 4-8% | 110-130 HV |
| Stress relieved at 300 C | 300-350 MPa | 180-230 MPa | 8-12% | 85-105 HV |
| T6 | 330-360 MPa | 230-260 MPa | 6-10% | 100-120 HV |
Unusually, as-built AlSi10Mg is stronger than the T6 condition. The fine silicon network from rapid solidification is lost on solution treatment, so T6 is chosen for uniformity rather than for strength.
Which Processes Can AlSi10Mg Powder Be Used In?
| LPBF | EBM | DED / cladding | MIM | Binder jetting | Thermal spray |

What Is AlSi10Mg Powder Used For?
Lightweight structural parts, heat exchangers and cold plates, automotive and motorsport components, and housings.
Post-processing
Stress relief at approximately 300 degrees C; T6 where higher strength is required.
Characterisation and Packing
Each batch is supplied with chemical analysis, particle size distribution by laser diffraction to ASTM B822, apparent and tap density, and flow rate by Hall or Carney funnel. Morphology imaging, oxygen and nitrogen analysis and reporting to ISO/ASTM 52907 are available where your qualification requires them.
Powder is packed under argon in sealed containers with desiccant, labelled with lot number, alloy, particle size cut and date of atomisation.
