China Atomized Metal Powder Supplier & Suppliers

Gas atomization employs high-pressure inert gases (Argon, Nitrogen) to break the molten metal stream into droplets, resulting in highly spherical particles with low oxygen pickup (<100–300 ppm) and high flowability, ideal for 3D printing and thermal spray. Water atomization utilizes ultra-high-pressure water jets, creating rapid quenching and irregular, angular particle shapes with higher surface oxide levels, preferred for traditional press-and-sinter powder metallurgy (P/M) requiring green strength.

Reactive and fine metal powders are packaged in UN-certified steel drums lined with multi-layer barrier foil or heavy-duty polyethylene bags. Prior to sealing, the inner headspace is evacuated and backfilled with high-purity dry argon gas (>99.999%). Desiccant packs and indicator strips are integrated to verify zero moisture ingress upon delivery at the destination port.

Yes. Our facilities accommodate custom stoichiometric compositions—including specialized Al-Mg, Zn-Al, and custom ternary formulations. Custom sizing is achieved through air classification, ultrasonic sieving, and cyclonic separation down to specific micron cuts (e.g., 0–20 μm, 15–45 μm, 20–63 μm, 45–106 μm) verified by laser diffraction reports.

Every lot is released with a comprehensive batch Certificate of Analysis (COA) specifying elemental chemistry (ICP/OES), interstitial gases (O, N, H via LECO), particle distribution curve (D10, D50, D90), apparent density, and Hall/Carney flow rates. GHS-format SDS and Technical Data Sheets (TDS) are provided with every order.

Standard stocked grades (such as standard Al-Mg spherical powder, zinc flakes, and industrial nitrates) typically ship within 7–14 days. Custom atomization runs or custom sieve fractions typically require 3–4 weeks lead time. MOQs vary by material category, typically starting at 100 kg for specialty alloy powders up to full container loads (FCL) for high-volume technical chemicals.
