Ultra-fine spherical morphology, narrow particle size distribution (PSD), and tailored surface chemistry matching global powder metallurgy standards.
Founded in 1997 and backed by Toyo Aluminium K.K. Group and Shanghai Matsuo Co., Ltd. since December 2009, Hunan Ningxiang JiWeiXin Metal Powder Co., Ltd. (Toyal JWX) represents an industry benchmark in spherical aluminium atomization and advanced metal injection molding (MIM) powders.
Our integrated manufacturing hub in the Ningxiang National Economic and Technological Development Zone operates with complete end-to-end governance: from induction furnace melting under inert atmosphere controls to multi-stage inert gas classification and automated packaging.
Harnessing closed-loop automation, in-line morphology scanning, and lean metallurgical supply chains to protect Tier-1 manufacturers from supply bottlenecks.
High-pressure inert-gas atomization lines eliminate surface oxides. Automated temperature and pressure loops guarantee that raw ingots transform into pristine spherical micro-particles.
Every production cycle integrates real-time laser diffraction analysis (Malvern Mastersizer standard), ensuring the critical D10, D50, and D90 parameters meet stringent injection flow requirements.
Strategically situated within China's key non-ferrous metallurgical corridor, securing uncompromised upstream aluminum supplies and maintaining an uninterruptible international supply chain.

Every shipped consignment contains a dedicated Certificate of Analysis indicating exact laser particle distribution, apparent density, and trace impurity levels.
Dedicated technical engineering liaison units covering North America, Western Europe, and Southeast Asia to support binder formulation development.
Explore high-purity, coated, and alloy variants engineered to accelerate powder metallurgy workflows and injection mold stability.
Comprehensive answers covering binder systems, debinding compatibility, customization, and export compliance.
For standard MIM feedstock processing, fine spherical powders with a D50 between 10 to 22 μm and a maximum top-cut (D97) below 38 μm provide the best balance. This size distribution maximizes green part shape retention, maintains high solids loading without rheological choking during molding, and facilitates complete densification during liquid-phase sintering.
Our facility employs an automated closed-circuit inert gas atomization line with continuously purified nitrogen and argon environments. The molten aluminum never contacts ambient air during break-up, classification, or screening. Sifted materials are transferred directly under inert conditions into vacuum-sealed multi-layer barrier drums to ensure oxygen content remains tightly regulated below specified ppm thresholds.
Our spherical morphology and neutral surface chemistry make our powders compatible with wax-polymer systems (paraffin wax, EVA, low-density polyethylene), catalytic polyacetal (POM) systems, and water-soluble binder solutions (PEG/PMMA). We also offer engineered surface-treated variants that prevent premature catalytic degradation and binder phase separation.
Yes. Utilizing advanced aerodynamic air classifiers and precision ultrasonic sieving systems, we can engineer custom multi-modal distributions (bimodal or trimodal packing curves) to achieve ultra-high packing densities, reduced binder volume fractions, and minimal sintering shrinkage.
Uncoated active aluminum powders are globally regulated as UN1396, Class 4.3 (water-reactive substances), whereas coated or phlegmatized powder forms fall under UN1309, Class 4.1 (flammable solids). We hold complete regulatory licensing, provide standard multi-language GHS Safety Data Sheets, and execute compliant sea and air freight through certified DG packing lines.
Leveraging Toyo Aluminium K.K.'s proven SPC (Statistical Process Control) principles, our 10,000-tonne capacity facility logs melting temperatures, nozzle differential pressures, gas flow velocities, and classifier rotor speeds under continuous computer supervision. Every production batch is validated via XRF, ICP-OES chemical analysis, and dynamic image flow testing prior to release.
