Verified production lots engineered for pyrotechnics, semiconductor electronics, thermal spray coatings, and specialized structural formulations.
In the transition toward next-generation additive manufacturing (AM), metal injection molding (MIM), and reactive energetics, the morphological accuracy of spherical metal powders determines application viability.
Utilizing high-pressure vacuum induction melting and ultra-pure inert gas atomization (VIGA/EIGA), our manufacturing ecosystem ensures sphericity coefficients exceeding 92%. This directly minimizes micro-satellite adhesion and virtually eliminates intra-particulate gas porosity.
By enforcing narrow Gaussian particle distributions (D10, D50, D90) calibrated via laser diffraction, powder formulations exhibit exceptional Hall flow rates (<20s/50g) and optimized apparent tap density, critical for consistent laser powder bed fusion (LPBF).
Specialized passivation regimes and protective gas packaging limit interstitial oxygen content (<150 ppm in critical titanium and aluminum matrices), mitigating cold-welding tendencies and stabilizing ignition kinetics in propulsion systems.

Gas atomization utilizes high-velocity inert gas jets (argon or nitrogen) to disintegrate molten metal streams into microscopic spherical droplets that solidify in-flight. Unlike irregularly shaped or faceted powders made through milling or chemical precipitation, gas-atomized spherical particles feature smooth surfaces, low friction, minimal satellite particles, and exceptional flowability. This morphology is mandatory for additive manufacturing (LPBF, EBM) and thermal spray because it guarantees uniform layer recoating, high packing density, and consistent bulk melting kinetics without trapping internal voids.
Atmospheric interstitial element pick-up is strictly countered through a closed-loop vacuum melting and atomization regime. Production occurs under high vacuum followed by inert gas backfill with ultrapure argon (up to 6N / 99.9999% purity). After atomization, sieving, blending, and packaging are completed inside cleanroom glovebox environments with oxygen and moisture levels constantly monitored below 10 ppm, preserving low ppm elemental purity throughout storage and transit.
Yes. Our engineering facilities regularly execute bespoke vacuum induction melting batches. Beyond standard 50:50 or 60:40 Al-Mg formulations, we tailor dopant elements (such as Scandium, Zirconium, or Rare Earths) and optimize target particle size cutoffs (e.g., 0–25 μm, 15–53 μm, 45–105 μm) based on your application equipment parameters and laser/electron beam energy densities.
Metal powders containing high reactive contents (such as aluminum, magnesium, or zinc) fall under UN Model Regulations Class 4.3 (substances which in contact with water emit flammable gases) or Class 4.1. Shipments are packed in heavy-duty UN-approved steel drums with anti-static barrier bags, desiccant packs, and inert gas seals. We manage full dangerous goods maritime clearance under the International Maritime Dangerous Goods (IMDG) Code, supported by valid dangerous goods packaging certificates and 16-section GHS SDS documents.
