3D Printing PowdersDelivering high-volume inert gas atomization metal powders that balance Japanese standard quality control with the rapid scalability of the Chinese supply network.
Jointly acquired in December 2009 by Toyo Aluminium K.K. Group and Shanghai Matsuo Co., Ltd., Toyal JWX implements Japanese monozukuri discipline. Every furnace heat, atomization run, and air classification stage is governed by automated statistical process control (SPC).
Located in the Ningxiang National Economic and Technological Development Zone (ETDZ), Hunan, our plant leverages direct pipeline integration with upstream electrolytic virgin liquid aluminium producers. This guarantees virgin input feedstock with iron and silicon impurities under 0.05%.
We are fully certified in ISO 9001:2015, ISO 14001:2015, and maintain a government-issued Safe Production License. As an experienced exporter of Class 4.3 (UN1396) and Class 4.1 (UN1309) reactive metal powders, we handle dangerous goods packaging, argon-purged UN steel drums, and international sea/air freight protocols.

| Evaluation Parameter | Toyal JWX Inert Gas Atomization (N2/Ar) | Conventional Water Atomization | Plasma Rotating Electrode (PREP) |
|---|---|---|---|
| Particle Morphology | Highly Spherical (Aspect Ratio < 1.08) with minimal satellite bonding | Irregular, nodular, tear-drop shapes with high internal porosity | Perfect spheres with near-zero satellite attachments |
| Oxygen Content (ppm) | Low to ultra-controlled (100 - 800 ppm) depending on grade | Very High (1,500 - 4,500 ppm) due to violent steam reaction | Ultra-low (50 - 200 ppm) but limited to rod electrode feeds |
| Hall Flowability (s/50g) | Superior (< 25s for 20-63μm); exceptional powder bed spread | Extremely poor; prone to jamming and mechanical interlocking | Excellent (< 20s); highly fluid flow dynamics |
| Economic Viability | High batch economy; scalable up to 10,000 metric tons/yr | Lowest upfront processing cost; restricted to low-spec PM parts | Prohibitively expensive; only viable for aerospace prototyping |
| Application Fit | LPBF, DED, MIM, AMMC, Electronic pastes, High-end pigments | Friction materials, basic chemical reagents, coarse press parts | Biomedical implants, critical rotational aero parts |
How our atomized metal powders solve weight, thermal degradation, and fatigue life challenges across leading sectors.
Additive manufacturing using AlSi10Mg and specialized Al-Mg-Sc (Scalmalloy equivalents) cuts structural payload weights by up to 45% while resisting orbital thermal cycling and sonic vibration stress.
Surface-coated spherical powders serve as high-volume thermal fillers in battery packs, potting resins, and onboard charger TIMs, reaching conductive thresholds over 6.0 W/m·K while maintaining dielectric breakdown margins.
By delivering d50 sizing around 10-15 μm with minimal fine dust clustering, our powders resolve the green compact deformation dilemma, yielding 98.5%+ theoretical density upon high-vacuum sintering.
Spherical aluminium powders act as critical deoxidizers and antioxidants in carbon-bonded MgO-C and Al2O3-C refractory bricks, sealing open porosity during steel ladle slag reactions.
How the green transition, additive mass-adoption, and nano-coating breakthroughs are redefining procurement expectations.
Traditional structural alloys (like AA7075 and AA6061) suffer from severe hot tearing during rapid laser re-solidification. Toyal JWX is pioneering the in-situ gas atomization alloying of trace nucleating agents (Zr, Sc, Ti) that homogenize equiaxed grain solidification, making high-strength alloys directly printable without micro-cracking.
Sourcing standards are tightening around particle satellites and internal closed gas pores. Our line incorporates multi-rotor dynamic air classification combined with ultrasonic screens, securing ultra-narrow particle size spans (D90/D10 < 2.5) while stripping away fine particles under 5μm that cause hazardous dust clumping.
For applications in water-based binders, moist storage, and reactive compounding, uncoated aluminium powder presents hydrogen-outgassing hazards. Toyal JWX’s proprietary silicon-organic and silica passivation coating wraps each sphere in a nanoscale barrier, extending shelf life over 24 months without diminishing sintering reaction kinetics.
Comprehensive answers regarding production quality, custom sieving, hazardous export compliance, and lot verification.
Yes. We engineer customized PSD distributions ranging from ultra-fine MIM fractions (0-20μm, 0-25μm), LPBF standard bands (15-53μm, 20-63μm), to coarse press-and-sinter profiles (up to 150μm). Furthermore, we formulate custom alloy melts (including Al-Si, Al-Cu, Al-Mg, and Al-Zn matrices) with minimum pilot order quantities, backed by full ICP-OES and laser diffraction COA reports.
Uncoated spherical aluminium powder provides maximum electrical and thermal conductivity alongside optimal metallurgical bonding in laser sintering, AMMC, and powder metallurgy. Coated (surface-treated) powders undergo liquid-phase organosilane or oxide passivation. This prevents hazardous hydrogen generation in moist resin environments, drastically drops paste viscosity, and promotes high filler loadings in automotive silicone thermal gap pads.
Atomized aluminium powders are strictly classified dangerous goods: Uncoated spherical powder is classified under UN1396 (Hazard Class 4.3 - Dangerous When Wet), while coated powders fall under UN1309 (Class 4.1 - Flammable Solid). We package products under inert argon or nitrogen gas shielding inside sealed anti-static foil liners, secured within UN-approved steel drums (50kg, 100kg, or 200kg). Every export shipment includes full IMDG/IATA compliant documentation, SDS sheets, and inspection certifications.
Our operations are certified under ISO 9001:2015 (Quality Management System) and ISO 14001:2015 (Environmental Management System), along with an official Safe Production License. Every production batch is tested via Malvern Mastersizer laser diffraction for D10/D50/D90 PSD, Hall Flowmeter for flowability, Scott Volumeter for tap density, and LECO analyzers for interstitial O, N, and H content.
Originally founded in 1997 in Hunan, the company was officially acquired in December 2009 by Japan's Toyo Aluminium K.K. Group in partnership with Shanghai Matsuo Co., Ltd. This corporate integration introduced Japan's benchmark monozukuri quality control and atomization safety standards to our 10,000-tonne facility, giving our global clientele the benefits of competitive Chinese base manufacturing backed by multinational accountability.
