Our centralized facility controls the closed loop from induction vacuum melting and supersonic inert gas atomization (N₂/Ar) to proprietary surface passivation, fulfilling high-volume industrial demand without batch variance.
International procurement directors leverage our integrated upstream-to-downstream metallurgy ecosystem to resolve cost, lead-time, and raw material volatility hurdles.
Strategically situated within China's premier non-ferrous manufacturing corridor, ensuring direct pipeline access to high-grade virgin ingot inputs (99.7% to 99.99% purity) with mitigated geopolitical shipping overheads.
Our dedicated agile atomization reactors allow tailored lot development (100 kg to multi-ton lots) within a fraction of standard lead times, adjusting PSD curves (D10, D50, D90) to match bespoke sintering presses and printing chambers.
High thermal-efficiency atomization, continuous in-line screening, and direct domestic smelting infrastructure yield 25-40% operational efficiencies over North American and European alternatives without sacrificing chemical purity.

Yes. By fine-tuning our gas nozzle geometry and operating dual-rotor air classification systems, we tightly adjust D10, D50, and D90 parameters. Whether your application requires 15–45μm for high-speed LPBF, sub-20μm for metal injection molding, or tailored bimodal distributions for high-density thermal greases, custom screening is standard protocol.
Uncoated spherical aluminium powder delivers clean metallic contact, essential for rapid liquid-phase sintering, laser melting, or AMMC matrix integration where high electrical and thermal conductivity is critical. In contrast, coated or surface-treated grades incorporate an ultra-thin organic or inorganic passivation shell that prevents polymer cross-linking poisoning, boosts silane coupling, and improves stability in high-humidity compounding environments.
Aluminium powders are classified internationally as Class 4.3 (water-reactive flammable solids, UN1396) or Class 4.1 (flammable solids, UN1309). We ship exclusively in UN-certified hermetically sealed steel drums lined with anti-static barrier film and positive-pressure inert argon blankets. All consignments are accompanied by compliant GHS-format Safety Data Sheets (SDS) and sea transport emergency declarations.
Our company is certified to ISO 9001:2015 and ISO 14001:2015 systems and maintains an active Safe Production License. Our testing laboratory is outfitted with certified Malvern Mastersizer laser diffraction systems, LECO oxygen/nitrogen analyzers, Hall and Carney flowmeters, and inductively coupled plasma (ICP) spectrometers. Every delivery is traceable back to the raw ingot heat number.
Hunan Ningxiang JiWeiXin Metal Powder Co., Ltd. was established in 1997. In December 2009, Toyo Aluminium K.K. Group along with Shanghai Matsuo Co., Ltd. jointly acquired the enterprise. This integration infused Japanese operational metallurgy standards, clean-atomization protocols, and global technical expertise into JiWeiXin's large-scale manufacturing infrastructure in Ningxiang, Hunan.
