Powder Metallurgy
Factory-direct micro-fine and spherical atomized powders synthesized under inert gas atomization processes for metallurgy, additive printing, and thermal polymers.
As decarbonization mandates accelerate across mobility, defense, and telecommunications sectors, the industrial shift toward high-performance light metal alloys has surpassed simple weight reduction.
Automotive OEMs face relentless challenges balancing EV battery weight with vehicle range. High-integrity magnesium die-casting alloys (such as AZ91D and AM60B) alongside micro-alloyed spherical aluminium powders (AlSi10Mg, Scalmalloy) deliver 30% to 50% structural mass savings over conventional cold-rolled steels, directly enhancing watt-hour efficiency per mile.
With the expansion of 5G base stations, optical transceivers, and AI hyperscale computing clusters, dissipation of excessive thermal flux requires next-generation polymer interface materials. Surface-coated, high-sphericity aluminium powders function as critical thermal conductive fillers without drastically altering compounding rheology or abrasive tool wear.
Laser Powder Bed Fusion (LPBF) and Direct Directed Energy Deposition (DED) have graduated from rapid prototyping to full series automotive and aerospace component production. The demand for sub-63μm spherical powders exhibiting high circularity, trace-oxygen passivity, and near-zero satellite agglomeration has grown at a 28.4% CAGR internationally.

| AZ91D Magnesium Grade | Mg - 9% Al - 0.8% Zn | 150 - 170 | 51 - 72 | Ultra-light Consumer Electronics & Drone Frames |
| High-Purity 4N Al (99.99%) | Unalloyed Low-Fe Matrix | 45 - 65 | 237 | Sputtering Targets & Photovoltaic Pastes |
| Al-SiC Metal Matrix (AMMC) | Alloy Matrix + 15-30% SiC Particulates | 350 - 480 | 160 - 190 | High-Speed Train Brake Discs & Substrates |
How our Ningxiang National-Level Economic & Technological Development Zone plant bridges Japanese precision metallurgical protocols with scalable, highly competitive Chinese upstream processing.
Inherited from Toyo Aluminium K.K. Group in 2009, our standard operating procedures mandate Japanese rigorous statistical process control (SPC), total trace impurity screening, and comprehensive batch lot isolation.
High-pressure supersonic nitrogen and argon atomization lines prevent uncontrolled surface oxidation during droplet freeze, ensuring high sphericity (≥0.92 circularity index) and extremely stable tap density.
Full UN Class 4.3 (UN1396) and Class 4.1 (UN1309) certification handling. We provide hermetic aluminum foil lining, argon nitrogen flushing, and complete export declaration clearance to 40+ nations seamlessly.
Located in central China's raw mineral refining hub, our 10,000 metric-ton output yields unparalleled purchasing leverage on A00 ingot feedstocks, translating to reliable, affordable OEM factory unit pricing.
Real-world deployment paradigms where particle morphology, chemical formulation, and packing densities determine manufacturing margins.
Engine mounting brackets, transmission steering housings, and air conditioning compressor components require uniform grain structures to prevent porosity. Our fine alloy powders enable press-and-sinter powder metallurgy and metal injection molding (MIM) operators to reach 98.5%+ theoretical density without post-sinter hipping.
For silicones, epoxies, and polyurethanes used in battery pack baseplates, regular spherical aluminium powders optimize packing density (bimodal PSD blending). Surface coating treatments prevent moisture-induced hydrogen gas outgassing, ensuring extended shelf life and 3.5 to 8.0 W/m·K bulk conductivity.
In continuous-casting MgO-C ladle bricks and Al₂O₃-C submerged nozzles, fine uncoated aluminium powder functions as a sacrificial deoxidizer. It reacts preferentially with ambient CO gas at steelmaking temperatures (900°C - 1400°C) to synthesize micro-crystalline Al₄C₃ and in-situ spinel crystals, protecting carbon structures from oxidation.
