About this product
A-Powder AlSi10Mg is a gas-atomized near-eutectic aluminium casting alloy for laser powder bed fusion (LPBF): low weight, high thermal conductivity and good strength-to-weight, heat-treatable (T6) for higher strength. US-produced, lot-certified for production.
Why engineers choose A-Powder AlSi10Mg
Four things a materials team verifies before qualifying a powder.
Light & strong
Dense aluminium parts at roughly a third of the weight of steel — high strength-to-weight for lightweight structures and moving parts.
High thermal conductivity
Excellent heat transfer — the default alloy for AM heat exchangers, cold plates and manifolds.
Lot-certified & heat-treatable
Full COA per lot (PSD, chemistry, density, flow). Stress-relief and T6 aging raise strength for structural parts.
US-produced, fast dispatch
Made in the USA and shipped from Los Angeles in 5–10 business days. Need a tighter cut or an official purchase request? Just ask.

Step 02
Tested & certified
Every lot checked for PSD, chemistry, apparent density and flow — full COA with a traceable lot number.
Step 03
Dispatched from LA
Bottled or hoppered and shipped from Los Angeles in 5–10 business days.

★★★★★
Same lot 4 times in a row. We stopped re-running parameter sweeps after the second order — density was identical to the first build.

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.
