Engineered for high sphericity, optimal packing density, and sub-surface chemical stability across Laser Powder Bed Fusion (LPBF), DED, and MIM platforms.
Additive manufacturing has transitioned rapidly from rapid prototyping to qualified high-throughput production. Sourcing high-purity, batch-traceable spherical metal powder is now the primary determinant of mechanical fidelity and total manufacturing yield.
Global aerospace, automotive, and defense sectors require substantial mass reductions without structural compromise. Lightweight alloy architectures designed via Generative Design and Topology Optimization demand raw powders with ultra-tight grain structures and zero hollow internal porosity.
Pure aluminium reflects more than 90% of standard 1064 nm fiber laser radiation, presenting severe molten pool instability. Modern OEM engineering resolves this through optimized alloying formulations like AlSi10Mg, Scalmalloy, and Al-Mn-Sc-Zr systems.
Global supply chain volatility has amplified the need for vertically integrated powder metallurgy foundries. Having end-to-end control from certified primary ingots down to precision cyclone screening guarantees batch repeatability for international OEM contracts.
Over 28 years of dedicated metallurgical atomization engineering
Scalable output powering global additive supply contracts

Strict adherence to ASTM B213, B214, and ISO 9001 specs
Engineered powder solutions tailored for challenging operational environments where mass, thermal dissipation, and dynamic fatigue life are decisive factors.
Additive manufacturing enables internal conformal cooling channels, thin-walled heat exchangers, and bracket consolidations that are impossible to machine with multi-axis CNC.
Electric vehicle architectures demand rapid thermal transfers and structural crashworthiness. Our atomized spherical alloy feedstocks empower next-generation EV platforms.
5G/6G RF microwave cavities and data center processing units generate immense localized thermal fluxes requiring ultra-dense, void-free dissipation substrates.
Combining spherical aluminium matrices with silicon carbide (SiC) or titanium carbide (TiC) micro-reinforcements produces hybrid composite components with steel-like rigidity.

Procuring fine metallic reactive powders requires absolute adherence to hazardous materials transport, dangerous goods customs protocols, and uncompromised quality governance.
Uncoated active aluminium powder is classified under international shipping conventions as UN1396 (Class 4.3 Water-Reactive), while coated grades fall under UN1309 (Class 4.1 Flammable Solid).
We provide full IMDG and IATA hazardous packaging: hermetically sealed steel drums, multi-layer vacuum foil liners, and argon-flushed atmospheres to prevent oxidation during maritime transit.
Every dispatch includes comprehensive batch documentation: ICP-OES elemental assay analyses, laser diffraction particle distribution charts (D10, D50, D90), and Scott volume bulk density metrics.
Our quality management is audited and certified under ISO 9001:2015 Quality Management and ISO 14001:2015 Environmental Management Systems with full raw-material traceability.
Our metallurgical team collaborates directly with additive machine engineers across Europe, North America, and the Asia-Pacific region to optimize parameter sets for diverse laser wavelengths and chamber kinematics.
We provide sample batch trials, recoater-friction assessments, and custom-tuned particle distribution curves to eliminate porosity in challenging custom alloys.
Pioneering the next frontier in advanced powder metallurgy: ultra-high-temperature alloys, circular powder reuse loops, and nano-functionalized particle surfaces.
Standard casting aluminium alloys experience severe strength decline above 150°C. Our R&D team is developing specialized Scandium-modified (Al-Mg-Sc-Zr) formulations that retain yield strengths exceeding 300 MPa at operating temperatures up to 250°C, bridging the performance gap with heavier titanium alloys.
Additive manufacturing cost-efficiency relies on powder recyclability. Repeated laser passes generate fine condensates and micro-satellites that diminish packing flow. We are developing specialized rejuvenation screening protocols and surface de-oxidation chemistry that enable 15+ re-use cycles without mechanical degradation.
By functionalizing atomized spherical powders with nanoscale ceramic coatings (such as SiC or TiB₂ nanoparticles) prior to printing, we enable grain refinement directly within the melt pool, preventing columnar grain growth and eliminating hot-tearing during laser scanning.
Direct metallurgical answers addressing particle size distribution, powder handling safety, machine compatibility, and international procurement standards.
Yes. Utilizing multi-stage ultrasonic and inert air-classifier sieving systems, we tailor powder cuts to target requirements. Standard AM distributions are 15–53 µm (LPBF), 45–105 µm (Direct Energy Deposition), and <20 µm (MIM). We provide customized D10, D50, and D90 parameters to match specific recoater mechanisms (blade vs. roller).
Spherical uncoated powder provides optimal flowability, minimal satellite attachment, and high tap density, making it ideal for laser powder bed fusion and powder metallurgy. Coated or surface-treated powders incorporate an organic or functional passivating monolayer, significantly enhancing compatibility with polymer resins (epoxy, silicone) for thermal fillers and dampening moisture reactivity.
Aluminium powders are classified as Dangerous Goods under UN1396 (Class 4.3 water-reactive substances) or UN1309 (Class 4.1 flammable solids). We package our materials in UN-certified hermetically sealed steel drums with vacuum-sealed inner aluminium-foil pouches flushed with dry argon to mitigate humidity ingress and ensure compliant international maritime and air freight clearance.
Our production facilities in the Ningxiang National Economic and Technological Development Zone operate under ISO 9001:2015 Quality Management and ISO 14001:2015 Environmental Management systems. Furthermore, the factory operates with an official National Safe Production License specifically covering reactive metal powder manufacturing and handling.
Hunan Ningxiang JiWeiXin Metal Powder Co., Ltd. was established in 1997. In December 2009, the organization was jointly acquired by Toyo Aluminium K.K. Group and Shanghai Matsuo Co., Ltd., integrating Japanese precision process discipline, strict purity standards, and global metallurgical testing protocols into our atomization infrastructure.
Inconsistent particle size or interstitial oxygen levels alter laser absorption depth and melt-pool viscosity, leading to lack-of-fusion voids or excessive vapor keyholing. Our vacuum induction melting and continuous inert gas atomization ensure that every lot exhibits uniform chemical composition, steady flow rates, and repeatable mechanical tensile results.
