We configure inert gas atomization nozzles (argon or nitrogen) coupled with precision multi-cyclone classification. We adjust flow speed and vortex angles to tailor the D10, D50, and D90 parameters precisely. For additive manufacturing (LPBF), we hold 15-53 μm with spherical morphology and zero satellites; for thermal fillers and MIM, we supply ultra-fine sub-20 μm powders with optimized packing density.
Uncoated spherical powder delivers peak elemental purity, high green strength for press-and-sinter powder metallurgy, and pristine molten pools in additive manufacturing. Coated (surface-treated) aluminum powder utilizes an organic or inorganic functional passivating layer. This prevents exothermic hydrogen outgassing in water-borne systems, dramatically lowers resin viscosity in silicone thermal pads, and optimizes mechanical bonding in composite formulations.
Corrosion prevention relies on a complete three-tier defense system: (1) rigorous chemical de-smutting and alkaline cleaning to eliminate surface intermetallic defects; (2) non-chromate zirconium/titanium nano-conversion coating that forms a 20-50nm passivated covalent base; and (3) electrostatic application of high-molecular-weight FEVE fluoropolymer or super-durable TGIC-free polyester cured at precise thermal curves to ensure cross-linking density exceeding 98%.
Dry atomized aluminum powder is subject to IMDG/IATA transport codes. Uncoated spherical aluminum is classified under UN1396 (Dangerous When Wet, Class 4.3), whereas coated varieties fall under UN1309 (Flammable Solid, Class 4.1). Our Ningxiang facility implements hermetically sealed, nitrogen-purged steel drums with inner anti-static moisture-barrier liners, certified for international seafreight and air transit with verified MSDS/SDS.
