Engineered for high sphericity, low satellite inclusion, controlled oxygen contents, and consistent flowability across LPBF, MIM, and thermal dissipation systems.
Combining the metallurgical traditions of Hunan Ningxiang JiWeiXin Metal Powder Co., Ltd. (since 1997) with the exacting operational methodologies of Japan's Toyo Aluminium K.K. Group (integrated 2009).
Over nearly three decades, our metallurgical teams have pushed the limits of inert gas atomization. We control physical particle dynamics from superheated liquid melt down to supersonic gas-jet impingement, ensuring uniform grain boundaries, repeatable apparent density, and near-zero satellite formation.
Jointly acquired in December 2009 by Toyo Aluminium K.K. Group and Shanghai Matsuo Co., Ltd., our lines implement stringent Japanese quality governance. Every master production order is subject to statistical process control, tracing raw ingot chemistry to final packaging under certified ISO 9001 and ISO 14001 frameworks.
Metal powders require strict hazard management. Holding China's certified Safe Production License, we coordinate direct dangerous-goods seafreight and airfreight according to UN1396 (Class 4.3 water-reactive powders) and UN1309 (Class 4.1 inflammable solids) with hermetic argon-purged barrier packaging.
A comprehensive analysis of metallurgical shifts, supply chain challenges, and criteria used by Fortune 500 procurement teams in qualifying tier-1 powder suppliers.
Additive manufacturing is no longer limited to non-critical bracket prototyping. Laser Powder Bed Fusion (LPBF), Direct Energy Deposition (DED), and Binder Jetting require thousands of kilograms of powder exhibiting identical thermal absorption and flow dynamics. Procurement teams demand powders that survive multiple re-use loops without progressive oxygen pickup or embrittlement.
High-speed recoating systems in commercial 3D printers can form voids or micro-trenches if fine powders agglomerate. Global buyers require custom-tailored Particle Size Distributions (e.g., 15-53 µm, 20-63 µm), low interstitial gas contents (<0.10% O2, <0.02% N2), and high Hall flow rates (<60 s/50g), directly lowering scrap rates on large-format multi-laser platforms.
Western aerospace and automotive clusters are exposed to localized supplier concentration and volatile raw metal surcharges. Sourcing qualified, high-tonnage powder from dedicated Chinese Tier-1 facilities provides vital supply chain resilience, hedging price risks while maintaining aerospace-grade Certificates of Analysis (COA).
Operating from our modern facility in the Ningxiang National Economic and Technological Development Zone, Toyal JWX integrates full-chain automation from pure ingot charging to vacuum packaging.
Our atomization towers operate under pressurized high-purity nitrogen and argon blankets. Advanced melt temperatures, nozzle geometries, and supersonic gas dispersion are regulated continuously via PLC feedback loops, mitigating batch-to-batch variations and preventing premature surface oxidation.
Tailored PSD demands absolute screening control. Toyal JWX integrates multi-stage cyclone classifiers and ultrasonic precision screens that divide atomized powder cuts with steep, narrow curves (D10, D50, D90) while eliminating airborne ultrafines (<10 µm) that pose flammability and flow problems.
Quality assurance is backed by an on-site laboratory featuring ICP-OES spectrometers, LECO oxygen/nitrogen/hydrogen analyzers, and Malvern laser diffraction particle analyzers. Every production lot leaves with an immutable chemical and physical Certificate of Analysis (COA).
From thin-walled thermal exchangers in electric vehicles to high-strain aerospace structural brackets, our aluminum powder solutions address specific mechanical and thermal boundaries.
AlSi10Mg and specialized Al-Sc/Al-Mg alloys for lightweight engine housings, drone airframes, and internal hydraulic manifolds requiring high strength-to-weight ratios and verified fatigue resistance.
Uncoated and surface-treated spherical powders designed as functional filler media for silicone gap pads, structural adhesives, and dielectric potting compounds across high-voltage battery enclosures.
Clean spherical matrix feedstocks engineered for thorough dry blending with silicon carbide (SiC) or titanium diboride (TiB2) reinforcements, producing high-stiffness, low-CTE brake components.
Sub-20 µm powders with low surface oxidation designed for compounding with polymer binders in Metal Injection Molding (MIM) and formulation into automotive brazing pastes for HVAC condensers.
Direct responses from our chief powder engineers regarding material selection, customization parameters, quality verification, and shipping procedures.
Yes. We engineer particle cut envelopes tailored directly to your additive manufacturing equipment, recoater style (rubber blade vs. roller), and layer thickness parameters. Standard options include 15-53 µm (LPBF), 20-63 µm (high-power LPBF), and custom sub-20 µm or 45-105 µm distributions for binder jetting, directed energy deposition (DED), and metal injection molding (MIM). Contact us with your D10, D50, and D90 parameters for custom configuration.
Spherical uncoated powder provides high metallic purity, electrical conductivity, and high tapping density, making it suitable for metallurgical fusion (3D printing, press-and-sinter PM, AMMC). Coated powder features an engineered organic or inorganic boundary layer. This surface treatment reduces surface activity, suppresses hydrogen gas evolution when exposed to trace moisture, and improves wetting and dispersion in silicone, epoxy, or urethane matrices for high-fill thermal management formulations.
Aluminium powder is classified under international dangerous goods protocols. Uncoated powders are typically booked as UN1396 (Class 4.3, Dangerous When Wet), while coated varieties often ship as UN1309 (Class 4.1, Flammable Solid). Toyal JWX provides full UN-tested certified steel drums or aluminum composite liners, current Safety Data Sheets (SDS in multi-language editions conforming to GHS Revision 9), maritime dangerous goods declarations (IMO/IMDG), and lithium battery pack testing compliance where relevant.
Our manufacturing plant operates under ISO 9001:2015 and ISO 14001:2015 certifications, holding an active municipal and provincial Safe Production License. Every lot is delivered with a Certificate of Analysis (COA) specifying elemental chemistry (ICP-OES), interstitial gases (O, N, H via combustion/inert gas fusion), full laser diffraction PSD (D10, D50, D90), and apparent/tap density according to ASTM B212/B527 standards.
Hunan Ningxiang JiWeiXin Metal Powder Co., Ltd. was established in 1997. In December 2009, the enterprise was formally acquired through a joint investment by Toyo Aluminium K.K. Group and Shanghai Matsuo Co., Ltd. The company operates as a key production hub within Toyo Aluminium's global specialty powders footprint, combining Chinese raw material access and high-scale manufacturing efficiency with Japanese metallurgical oversight and quality control standards.
