Explore our top-tier atomized uncoated, alloy, and functionalized powders engineered for additive manufacturing, thermal fillers, and metal matrix composites.
Connecting Japanese Metallurgical Precision with Advanced High-Volume Chinese Manufacturing Infrastructure.
Founded in 1997 as Hunan Ningxiang JiWeiXin Metal Powder Co., Ltd., the enterprise established itself as a pioneer in advanced gas atomization. In December 2009, a landmark global integration occurred when the company was jointly acquired by Toyo Aluminium K.K. Group (TOYAL) and Shanghai Matsuo Co., Ltd.
This strategic alliance merged Toyo Aluminium's century-long leadership in powder metallurgy, pigment engineering, and strict Japanese Quality Assurance (QA) with Ningxiang's vast industrial footprint and raw material supply chain efficiency.
Operating from the state-level Ningxiang Economic and Technological Development Zone in Hunan, China, Toyal JWX enforces world-class standards across every step of production. Integrated inert-gas atomization lines guarantee zero cross-contamination and sub-ppm impurity control.
With an annual production capacity exceeding 10,000 metric tons, Toyal JWX serves over 230 enterprise partners across Europe, North America, Japan, South Korea, and Southeast Asia, adhering strictly to ISO 9001:2015 and ISO 14001:2015 standards.
Unlike standard air-atomized powders that exhibit irregular, acicular morphologies and variable oxide skin thickness (3-10 nm), Toyal JWX utilizes proprietary inert gas atomization (N₂/Ar atmosphere). This achieves near-perfect sphericity (>0.95 aspect ratio), a micro-thin uniform oxide layer (<2 nm), exceptionally low interstitial gas content, and a tap density reaching up to 65% of theoretical solid density.
Pioneering tomorrow's powder metallurgy through inert gas atomization, fine-particle classification, and functional surface modification.
Precision control of supersonic nozzle aerodynamics allows tight tailing of Particle Size Distribution (PSD). From fine cuts (D50 = 3–15 µm) for MIM and thermal fillers to medium cuts (D50 = 20–63 µm) for Laser Powder Bed Fusion (LPBF), satellite-free powder beads ensure superior flowability (Hall Flow < 25 s/50g).
To tackle moisture sensitivity and hydrogen gas evolution in high-humidity applications, Toyal JWX has developed silane coupling, organosilicon encapsulation, and nano-silica modification technologies. Coated powders deliver higher chemical stability without compromising thermal conductivity or sintering kinetics.
Looking toward 2030, our R&D roadmap focuses on high-strength aluminium alloy powders (7000-series, Al-Mg-Sc-Zr Scalmalloy types) and ultra-pure matrix powders optimized for ceramic reinforcement (SiC, Al₂O₃, TiB₂) blending, creating ultra-lightweight structural metal matrix composites.

From aerospace structures to electric vehicle battery management, Toyal JWX powders serve as crucial materials across high-growth sectors.
High thermal conductivity (>200 W/m·K) and spherical packing enable exceptionally high filler loadings (up to 85 wt%) in silicone grease, gap pads, phase change materials, and epoxy adhesives. Spherical geometry maintains low shear viscosity for smooth dispensing in EV battery module thermal interfaces and 5G base stations.
Pre-alloyed powders including AlSi10Mg, AlSi12, AlSi7Mg, and custom 6000/7000 series engineered specifically for SLM/LPBF platforms. Controlled low oxygen content (<0.08%) prevents optical reflection interference during laser melting, achieving fully dense (>99.8%) printed parts with isotropic tensile strength.
Serving the defense, railway, and automotive braking industries. Uncoated pure and alloyed spherical powders act as the matrix binder when liquid-phase sintered or hot-isostatically pressed (HIP) with SiC or B₄C ceramic reinforcement particles, producing lightweight components with ceramic-like wear resistance.
Combining scalable advanced manufacturing infrastructure in Ningxiang with rigorous quality monitoring systems.
Toyal JWX’s manufacturing facility utilizes fully enclosed closed-loop atomization towers equipped with online laser diffraction size analyzer systems. Melting temperature, atomization gas pressure, oxygen partial pressure, and powder feed rates are continuously logged via SCADA networks, eliminating batch-to-batch variation.
Located adjacent to primary electrolytic aluminium production bases in Central/South China, Toyal JWX secures top-tier primary aluminium ingots (>99.85% purity) with direct access to regional energy grids. This strategic position guarantees uninterrupted raw material pipelines, competitive pricing models, and fast buffer stock mobilization for global buyers during supply disruptions.
Custom particle size distributions, proprietary alloy chemistry synthesis, and standardized international dangerous goods logistics support.
Whether your process requires tight monodisperse distributions, bimodal packing curves for maximum tap density, or ultra-fine fractions (<5 µm), our air-classifier systems can be tailored to meet your target specifications.
Toyal JWX accepts custom master alloy melting orders for specialized chemical ratios—including Al-Si, Al-Mg, Al-Cu, Al-Zn, and rare-earth dopants—backed by full ICP-OES and LECO oxygen/nitrogen analytical reports.
Exporting fine metal powders requires stringent safety compliance. We provide UN-certified steel drums (25 kg to 200 kg) with vacuum aluminum-foil inner lining, argon or nitrogen purge, moisture-proof desiccants, and international UN markings.
