Manufactured under Japanese Toyo Aluminium K.K. process standards to deliver uniform sphericity, low surface oxidation, and precise particle size classification.
As an integrated entity of the world-renowned Toyo Aluminium K.K. Group, Hunan Ningxiang JiWeiXin Metal Powder Co., Ltd. (Toyal JWX) drives global standards in the spherical atomization of light alloys.
Toyal JWX merges decades of Japanese technological rigor with modern production ecosystems. Our closed-loop nitrogen gas atomization lines ensure unyielding consistency in grain sphericity, packing density, and oxide-skin passivation.
We tailor aluminum organizations from elemental powder alloying (AlSi10Mg, AlSi7Mg, Scalmalloy-equivalents, 2xxx, 6xxx, and 7xxx series) to bespoke particle morphology classifications, ensuring maximum packing efficiency for each unique application.
Certified to export Class 4.1 (UN1309) coated powders and Class 4.3 (UN1396) water-reactive dry powders across the globe. Our argon-purged, hermetic moisture-proof IBC and steel-drum packaging ensures complete safety and zero degradation upon delivery.
The industrial landscape for aluminum powder has shifted from legacy pyrotechnics and pigments into ultra-engineered functional metallics driving decarbonization, aerospace weight reduction, and next-generation microelectronics.
Additive manufacturing requires atomized particles with spherical circularity exceeding 0.92, narrow D10-D90 distribution spans, and zero internal satellite particles. Industrial organizations are standardizing custom aluminum alloy grades to balance high thermal dissipation with crack-free solidification under high-energy laser sintering.
High-density battery modules and SiC power inverters require unprecedented thermal transfer. Advanced surface-passivated spherical aluminum powder serves as a high-loading conductive filler for silicone gels and epoxy formulations, providing superior thermal conductivity without excessive paste viscosity.
Aluminum Metal Matrix Composites (AMMC) combining high-purity aluminum matrix powders with SiC, AlN, or graphene reinforcements replace heavy steel and titanium components in aerospace braking mechanisms, precision optic housings, and semiconductor robotics where structural stiffness is non-negotiable.
Procurement directors and metallurgical engineers require verifiable batch stability, low oxygen pick-up, and predictable bulk densities to avoid process failure in automated lines.

Translating atomized aluminum powder characteristics into breakthrough industrial advantages across aerospace, power electronics, and structural manufacturing.
Combines low density with high specific stiffness. Our gas-atomized AlSi10Mg and high-strength custom alloys yield parts with 99.8% relative density, eliminating internal porosity in critical engine brackets and heat exchangers.
Surface-treated and silane-coated spherical powders allow maximum filling ratios (>75 vol%) in polymer resin matrices. This reduces thermal boundary resistance for EV inverters, DC-DC converters, and battery chill plates.
Fine sub-20 micron alloy powders specifically designed for metal injection molding (MIM). High green strength after debinding allows net-shape production of mobile frames, camera mounts, and wearable frames with zero machining waste.
Uncoated micron-scale aluminum powders used in MgO-C and Al₂O₃-C refractory bricks. When exposed to extreme steelmaking heat, the aluminum forms in-situ AlN and spinel bridges that prevent carbon burnout and extend ladle lifetime.
As a verified production enterprise operating under ISO 9001 and ISO 14001, Toyal JWX maintains multi-layered safety systems for compliant handling and ocean shipment of reactive light metals.
Full batch genealogy tracking from incoming ingot smelting to final gas classifying. Every export consignment is paired with standard Certificates of Analysis (COA) detailing ICP-OES elemental assay, Malvern Mastersizer laser diffraction PSD, and LECO gas analysis.
Aluminum powder is subject to IMDG, ICAO, and ADR regulations. Uncoated powders (UN1396) and coated powders (UN1309) are packed in UN-certified steel drums with internal nitrogen-flushed poly liners, accompanied by multilingual Safety Data Sheets (GHS SDS).
Supported by the global sales network of Toyo Aluminium K.K. and Shanghai Matsuo Co., Ltd., we provide real-time customs clearance, consignment buffer stocking, and technical assistance across North America, Europe, Japan, and Southeast Asia.
Our ongoing technical development targets lower carbon intensity, sub-micron powder control, and novel hyper-eutectic alloys tailored for gigawatt-class industrial demands.
Developing 100% recycled scrap-to-spherical powder conversion lines using secondary high-grade aircraft scrap. Closed-loop inert gas recovery lowers energy consumption by up to 34% per metric ton of atomized aluminum.
Moving beyond standard eutectic Al-Si alloys into customized Sc, Zr, and Ti micro-alloyed aluminum powders. These advanced chemistries suppress high-temperature grain coarsening, maintaining yield strength up to 350°C in aerospace engine shrouds.
Pioneering gas-phase organic-inorganic hybrid nano-coatings that impart electrical insulation to conductive aluminum spheres, allowing design engineers to manufacture ultra-thin thermal pads with zero dielectric breakdown risk.
Clear, definitive technical answers to assist sourcing managers, laboratory directors, and manufacturing executives in qualifying Toyal JWX aluminum powders.
We deploy closed-loop ultrasonic precision air classifiers and aerodynamic vortex cyclonic systems calibrated against laser diffraction standards (Malvern 3000). We can tightly calibrate D10, D50, and D90 parameters, eliminating both ultra-fine "dust" that impairs flow and oversized satellites that cause defects in 3D printing and MIM.
Uncoated spherical aluminum powder is regulated under UN1396, Class 4.3 (Dangerous When Wet), requiring hermetically sealed steel drums with secondary desiccant bags and nitrogen blanket purge. Coated or surface-treated aluminum powders that pass water-immersion reaction tests are classified as UN1309, Class 4.1 (Flammable Solid), simplifying multimodal transit logistics.
Yes. Our in-house induction vacuum melting and inert gas atomization infrastructure allows full ODM batch production of proprietary alloy recipes. Whether your formulation requires controlled trace additions of zirconium, scandium, copper, or high silicon fractions (up to 40% Al-Si), our metallurgy team manages composition to within ±0.05% tolerance.
Every commercial batch is accompanied by an inspection certificate conforming to EN 10204 3.1. This includes full elemental chemical breakdown via ICP-OES, apparent and tap densities, Hall flow speed (ASTM B213), oxygen/nitrogen/hydrogen ppm content via inert gas fusion, and SEM photographic records verifying morphology.
Irregular or flake powders create severe frictional resistance when suspended in silicone oils, rapidly causing high mixture viscosity even at low solid loadings (40-50 wt%). Our high-sphericity atomized aluminum achieves low surface friction, enabling formulations with over 80 wt% solids loading while maintaining pumpability for automated paste dispensing.
When stored in original, unopened hermetically sealed drums in a climate-controlled warehouse (temperature ≤ 30°C, relative humidity ≤ 60%), our spherical powders offer a guaranteed shelf life of 24 months. After opening, resealing with an argon backfill prevents moisture adsorption and gradual surface oxidation.
