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.

Questions on ferrite content, flowability, recyclate ratios, or HIP response? A materials engineer answers directly — not a contact-form bot. Most replies in under 4 hours, NDA standard.
About this product
AVIMETAL AlSi10Mg is a lightweight aluminum casting alloy for laser powder bed fusion (LPBF), ideal for parts that need low weight, complex geometry and good thermal properties. The silicon-magnesium chemistry gives increased strength and hardness while staying easy to finish (spark-eroded, welded, shot-peened, polished, coated).
Produced by AVIMETAL, a leading specialist manufacturer of additive-manufacturing metal powders with in-house liquid-metal atomization and a strong aerospace and automotive track record.
Why teams buy this powder from Additive Plus
- Genuine AVIMETAL AlSi10Mg — gas-atomized for high sphericity, low oxygen and consistent flow.
- A strong value alternative to premium Western aluminum powders, at an accessible, published price.
- Available in small, workable volumes — no large mill minimums.
- Full COA with every lot — PSD, chemistry, apparent density and flow rate, with a traceable lot number.
- Fast dispatch from Los Angeles. Custom alloys / cuts via our own in-house atomization.
Standards & equivalents
- Made to the AlSi10Mg specification: EN AC-43000 · A360 (near-equivalent casting alloy)
- Machine type: F — LPBF · Particle size: 20–63 µm (custom cuts available) · Bottle: 10 kg / 22 lbs
- Quality: gas-atomized on dedicated AVIMETAL lines for high sphericity and low oxygen; full COA per lot.
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% |
| Magnesium (Mg) | 0.20–0.45% | Manganese (Mn) | ≤ 0.45% |
| 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.

Unedited feedback from customers who reorder Aluminum Powder AlSi10Mg | 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 quantity do you sell — can I order a small amount?
Yes. We stock this AVIMETAL alloy and sell it in accessible quantities — a 10 kg bottle as standard, with larger production volumes available. Most mills require large minimums and hide pricing behind an account; we keep it simple with a clear, published price and small-lot availability. Need a different volume? Just ask.
Do you provide a Certificate of Analysis (COA)?
Every lot ships with a full COA — particle size distribution, chemistry, apparent density and flow rate — plus a traceable lot number, so you can qualify once and reorder the same material with confidence.
