What your process engineer actually checks
Locked, traceable lot chemistry
Every lot ships with a COA documenting PSD, sphericity, flow rate, apparent density, and full chemistry — and a lot number you can trace. Aerospace and medical teams reorder 4+ times without re-qualifying.
Qualified parameters, not just powder
Validated parameter sets for EOS M 290, Renishaw 500Q, SLM 280, and our own AO Metal LPBF ship with the order. Load the profile and hit density on the first build — no parameter-development burn.

Chemical composition
Typical chemistry (wt%) for AlSi10Mg:
| Element | Content | Element | Content |
|---|---|---|---|
| Aluminum (Al) | Balance | Titanium (Ti) | ≤ 0.15% |
| Silicon (Si) | 9.00–11.00% | Zinc (Zn) | ≤ 0.10% |

| Iron (Fe) | ≤ 0.55% | Copper / Nickel | ≤ 0.05% each |
Heat treatment & processing
- Heat-treatable — a T6 cycle (solution anneal, quench, age) can be applied after the build to raise strength and hardness.
- Stress relief is commonly used before part removal.
- Easy to finish: spark-erosion, welding, micro shot-peening, polishing and coating.
Key performance benefits
- Lightweight aluminum alloy
- High thermal conductivity
- Good corrosion resistance
- Good strength and hardness from the Si-Mg chemistry
- Excellent weldability and easy post-processing
Typical applications
- Lightweight brackets
- Valves and ducts

Unedited feedback from customers who reorder A-Powder AlSi10Mg Aluminum Powder for Metal 3D Printing | LPBF Compatible – 10 kg / 22 lbs.
★★★★★
Same lot 4 times in a row. We stopped re-running parameter sweeps after the second order — density was identical to the first build.

★★★★★
Asked about ferrite content on a Friday. A materials engineer answered Monday morning with actual data, not a sales pitch. That's why we keep ordering.

COA matches the bottle. PSD and flow are exactly what was on the sheet — we run it on a Renishaw 500Q and it hits density on the first try.

Common questions
Don't see yours? Email [email protected] — NDA standard, typical reply within 4 hours.
What is AlSi10Mg Aluminum Powder?
A gas-atomized, LPBF-optimized aluminum alloy powder with high Si content, engineered for lightweight, thermally efficient components with consistent mechanical properties and repeatable builds.
Which AM processes is it compatible with?
Optimized for LPBF (Laser Powder Bed Fusion). Its spherical morphology and controlled PSD (15–53 µm) ensure smooth recoating, stable layer fusion, and minimal spatter.
Can this material be heat-treated?
Yes, heat treatment enhances tensile strength and yield (UTS 300 MPa, yield 185 MPa) while maintaining good elongation (~12 %).
What industries typically use AlSi10Mg?
Aerospace, transportation, automotive, and industrial manufacturing sectors.
Why choose A-Powder AlSi10Mg?
Manufactured by AO Metal using VIGA with tight PSD, low oxygen content, small-batch availability, fast delivery, and full traceable documentation, ensuring reliable production-ready performance.
Is A-Powder the same quality as name-brand metal powders?
Yes. A-Powder is our own brand of industrial AM powder - gas-atomized for high sphericity and low oxygen, with a full Certificate of Analysis (chemistry, particle-size distribution, apparent density and flow rate) on every lot. You get the performance you expect from a premium feedstock, at a more accessible, published price.
Can I order a smaller quantity or a custom particle size?
Yes. We sell in small, workable volumes with no large mill minimums, and we can supply custom particle-size cuts or quantities on request - just ask us for a quote.
