Explore our core atomized powders engineered to exact particle size distribution (PSD), controlled tap density, and minimum oxygen pickup for demanding manufacturing routes.
Founded in 1997 in Hunan Ningxiang Economic and Technological Development Zone, Hunan Ningxiang JiWeiXin Metal Powder Co., Ltd. (Toyal JWX) represents an elite tier in atomized aluminum powder synthesis. Jointly acquired in December 2009 by Toyo Aluminium K.K. Group and Shanghai Matsuo Co., Ltd., the factory operates at the nexus of world-class Japanese manufacturing discipline and China's high-efficiency metallurgical supply infrastructure.
Unlike standard commodity brokers, Toyal JWX oversees the entire value trajectory: primary smelting, nitrogen and argon inert gas atomization, cyclone aerodynamic sizing, chemical surface passivating, and airtight inert packaging. Our proprietary atomization nozzle geometry ensures exceptional sphericity (>92%), minimized satellite particulate, and near-zero void formation, delivering reliable melt kinetics across laser additive manufacturing and precision net-shape sintered powder metallurgy.
Every production batch undergoes comprehensive ICP-OES chemical analysis, laser particle diffraction (Malvern Mastersizer 3000), Hall flow rate calibration, and SEM morphological validation before shipping.
Why Tier-1 international defense, aerospace, automotive, and electronics conglomerates consolidate their supply contracts with our Hunan automated manufacturing base.
Situated within Hunan's specialized metallurgical economic corridor, our plant benefits from uninterrupted access to primary electrolytic virgin aluminum (A00 grade, Al ≥ 99.70% and ultra-pure 99.99%). This direct upstream smelting coupling shields our global clients from volatile regional spot market markups and raw ingot supply crunches.
Our facility runs high-pressure closed-circuit recycling inert gas atomization towers. By re-purifying nitrogen and argon carrier gases in real time, our production line dramatically lowers energy-intensive overheads while preventing unpredictable atmospheric humidity ingress. This yields high-purity powder with lowest-in-class dissolved hydrogen content.
Leveraging deep operational familiarity with Shanghai, Ningbo, and Shenzhen maritime terminals, we manage Dangerous Goods Class 4.3 (UN 1396) and Class 4.1 (UN 1309) customs clearances smoothly. Through dedicated UN-approved steel drum packaging with nitrogen blankets, we eradicate transit oxidation and port inspection delays.
Procurement teams require distinct particle morphologies, flowability metrics, and chemical boundary tolerances across varied end-manufacturing techniques.

Crossing international borders with fine metallic powders requires stringent legal conformance, hazardous material documentation, and verified environmental auditing.
All exported atomized aluminum and specialized alloy grades fully conform to EU REACH Regulation (EC No 1907/2006) and RoHS Directive 2011/65/EU, guaranteeing absence of SVHC hazardous substances, lead, cadmium, and hexavalent chromium.
Uncoated powders (UN 1396, Hazard Class 4.3, substances which emit flammable gases when wet) and coated formulations (UN 1309, Class 4.1) ship in UN-certified steel drums with moisture-impervious foil liners and nitrogen gas purging.
Every single pallet is labeled with unique QR-linked batch lineage. Certificates of Analysis (COA) document real-time laser diffraction distributions (D10, D50, D90, D97), true density, bulk density, Hall flow rate, and trace impurity limits.
Supported by Toyo Aluminium group networks across Europe, Southeast Asia, Japan, and the Americas, our sales engineers provide localized metallurgical consultation, trial powder runs, and rapid customs brokerage clearance guidance.
The transition toward electric mobility, decarbonized aviation, and high-frequency edge computing is reshaping technical powder engineering requirements.
Global OEMs now evaluate Scope 3 carbon footprints rigorously. Toyal JWX is progressively incorporating certified low-carbon electrolytic aluminum ingots powered by hydroelectricity from Southern China, allowing aerospace and automotive customers to meet net-zero targets without sacrificing raw purity.
Conventional 6000 and 7000 series aluminum grades suffer severe hot cracking during laser powder bed fusion (LPBF). Our R&D engineering lab has developed proprietary Al-Mg-Sc-Zr and modified Al-Mn-Ce powders featuring in-situ grain boundary nucleating agents, eliminating micro-tearing and enabling tensile strengths exceeding 520 MPa.
As 800V EV battery architectures demand higher thermal dissipation, thermal interface materials require filler loadings exceeding 80% by weight. Our organosilicon functionalized aluminum particles prevent premature resin thickening, maximizing isotropic thermal conductivity up to 4.5 W/m·K while keeping viscosity dispensable.
From microelectronics thermal potting to lightweight structural chassis components, our specialized powders resolve foundational engineering challenges.
Utilizing gas-atomized AlSi10Mg with narrow particle sizing (20-53 μm) enables additive manufacture of ultra-thin wall heat exchanger fins (≤ 200 μm) with leak-tight integrity. Vacuum-annealed components resist thermal fatigue across severe cryogenic to high-heat operating cycles.
Our spherical Al-Si eutectic powder (Al4047 grade) features a strictly uniform 11-12% silicon mass fraction. Blended into brazing pastes for controlled atmosphere brazing (CAB) of vehicle radiators, it produces uniform fillet joints without flux inclusions or blistering.
Clean uncoated atomized aluminum powder forms an optimal matrix when blended with silicon carbide (SiC) or boron carbide (B4C) particulates. Used in high-performance braking discs and semiconductor wafer chucks, AMMC delivers exceptional specific stiffness and low thermal expansion.

Through multi-stage cyclonic air classification and ultrasonic precision sieving, we tailor bespoke cutoffs including 15-45 μm, 20-53 μm, 20-63 μm, or sub-20 μm fractions. Clients specify target D10, D50, and D90 parameters, and we deliver narrow standard deviations (±1.5 μm on D50) to prevent segregating or erratic recoater spreading in laser 3D printers.
Spherical uncoated aluminum powder features an unadulterated passivated native oxide layer (∼2-4 nm Al2O3), optimizing electrical and thermal conductivity for additive manufacturing, sintering powder metallurgy, and composite matrices. Surface-coated aluminum powder incorporates nanometer-thin coupling agents (such as silanes or stearates) to inhibit reactive gassing in humid environments and promote rheological dispersion into silicone or epoxy potting compounds.
Aluminium powders are classified under International Maritime Dangerous Goods (IMDG) codes. Pure atomized fine powders fall under UN 1396 (Class 4.3 Water-reactive solids), whereas coated variants typically classify under UN 1309 (Class 4.1 Flammable solids). We provide comprehensive UN-rated steel drums, vacuum nitrogen bagging, verified MSDS in 12 languages, and official dangerous cargo declaration forms.
Hunan Ningxiang JiWeiXin Metal Powder Co., Ltd. operates under dual ISO 9001:2015 and ISO 14001:2015 systems audited by CQC. Furthermore, our specialized plant holds an official Safe Production License for pyrophoric and hazardous metal atomization issued by state emergency management departments, guaranteeing uncompromised operational sustainability.
Established in 1997, the company entered an international joint venture in December 2009 when it was acquired by Toyo Aluminium K.K. Group and Shanghai Matsuo Co., Ltd. This corporate integration introduced Japanese process governance, Kaizen quality principles, and proprietary atomization nozzle tech to our massive Hunan production base.
