What your process engineer actually checks
Locked, traceable lot chemistry
A COA on request documents PSD, sphericity, flow rate, apparent density, and full chemistry — and a lot number you can trace.
A materials engineer on the line
Questions on ferrite content, flowability, recyclate ratios, or HIP response? A materials engineer answers directly — not a contact-form bot. NDA standard.
PowderRange® 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 keeping the part easy to finish — it can be spark-eroded, welded, micro shot-peened, polished and coated.
Like cast AlSi10Mg, printed parts can be heat-treated (for example a T6 cycle of solution annealing, quenching and age hardening) to lift mechanical properties. It also has excellent weldability in laser AM.
Why teams buy this powder from Additive Plus
- Genuine Carpenter PowderRange® AlSi10Mg — gas-atomized for high sphericity, low oxygen and consistent flow.
- Available in small, workable volumes. Most mills sell large minimums and hide pricing behind an account. We stock this alloy and sell it in accessible quantities at a clear, published price.
- COA on request — particle size distribution, chemistry, apparent density and flow rate, with a traceable lot number.
- In US stock — ready to ship. Order online in minutes.
- Need a custom alloy or a tighter cut? We also run our own atomization in-house and can produce custom small-batch powder on request — separate from this stocked product.

Chemical composition
Typical chemistry (wt%), per the Carpenter PowderRange® datasheet:
| Element | Content | Element | Content |
|---|---|---|---|
| Aluminum (Al) | Balance | Titanium (Ti) | ≤ 0.15% |
| Silicon (Si) | 9.00–11.00% | Zinc (Zn) | ≤ 0.10% |

| Lead / Tin | ≤ 0.05% each | Nitrogen (N) | ≤ 0.05% |
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 to reduce residual stress before part removal.
- Easy to finish: spark-erosion, welding, micro shot-peening, polishing and coating are all compatible.
