In modern material science and high-end industrial engineering, Spherical Aluminum Powder represents a foundational building block for technological growth. Distinguished by its high active aluminum content, uniform sphericity, and controlled particle size distribution (PSD), this material is essential for advanced metallurgy, aerospace engineering, additive manufacturing, and specialty chemical synthesis.
At Yanxatech System Industries Limited (YANXA), we leverage over a decade of processing and manufacturing expertise (established in 2008) to deliver premium atomized metallic solutions. Unlike standard flake or irregular aluminum powders, spherical configurations exhibit exceptional flowability and high tap density. This minimizes spatial voids during packaging and dynamic application, ensuring optimal thermodynamic and kinetic performance in energetic formulations and solid-state construction.
Our manufacturing facility utilizes state-of-the-art nitrogen gas atomization systems. This setup strictly limits external contaminants, maintaining oxygen levels under controlled thresholds to guarantee safety, operational stability, and consistency across batches.
The mechanical and chemical properties of Spherical Aluminum Powder depend heavily on its manufacturing method. YANXA, alongside partner research institutes, relies on the Inert Gas Atomization (IGA) pathway to process high-purity raw ingots into uniform, microscopic spheres.
During the process, raw aluminum ingots are melted in a controlled induction furnace. The liquid metal is then directed through a technical refractory nozzle, where it is struck by high-velocity, high-pressure inert gases (typically Nitrogen or Argon, depending on the chemical specifications required by the client). This supersonic gas stream disintegrates the molten metal stream into micro-droplets. Thanks to surface tension, these droplets solidify into near-perfect spheres as they fall through the cooling chamber.
We supply powders classified into exact distribution ranges (e.g., D10, D50, and D90 metrics) ranging from 1 to 150 microns. This customization ensures compatibility with different industrial feedstocks.
By using closed-loop nitrogen and argon recycling systems, we prevent oxide formation on the particle surfaces. This results in highly active chemical reactants and consistent alloy qualities.
High sphericity reduces friction between particles during transport, powder bed compaction, and injection molding. This property optimizes viscosity and loading in compound materials.
Yanxatech System Industries Limited (YANXA) has grown from a specialized business unit in 2008 into a leading supplier of high-performance materials in China. Our growth is driven by a focus on chemical and metallurgical innovations. Today, we work alongside top national laboratories and certified manufacturers to export high-grade specialty chemicals, liquid rubbers, nitrates, and metal powders globally.
Our core operating philosophy is simple: Quality, safety, and efficiency prevail over all values in our business. Chemicals and metal powders demand rigorous safety and quality management. We adhere strictly to ISO standards, safety guidelines, and environmental protections to protect both operators and the environment.
Beyond spherical aluminum and alloy powders, YANXA provides a diverse selection of specialty organic compounds, liquid rubbers, and industrial gases. Below are technical breakdowns of our key products:
Formaldehyde is a highly active organic compound. It is commercially supplied as formalin—a 37% to 50% aqueous solution containing a controlled amount of methanol as a polymerization inhibitor.
HMTA is a white crystalline powder synthesized via the condensation reaction of high-purity formaldehyde and ammonia.
Paraformaldehyde (PFA) is a solid, polymerized form of formaldehyde. It releases formaldehyde gas upon heating, making it ideal for processes requiring anhydrous formaldehyde.

By blending magnesium and aluminum at the molecular level prior to gas atomization, YANXA produces highly homogeneous Al-Mg Alloy Powders. These powders offer high reactivity, controlled combustion speed, and corrosion resistance, making them crucial components in defense pyrotechnics and aerospace solid propellants.
Our spherical metallic powders and raw materials serve several high-tech industries globally:
In metal 3D printing (such as Selective Laser Melting - SLM), spherical powders must flow smoothly across the powder bed. Our optimized spherical powder minimizes defect rates, micro-cracks, and internal voids, yielding components that meet strict aerospace tolerances.
Spherical aluminum powder is a key ingredient in conductive aluminum paste used for solar silicon wafers. High purity and consistent particle size ensure optimal sintering, low resistance, and improved energy conversion rates.
Aluminum powder is classified as a hazardous material (UN 1396, Class 4.3 water-reactive, or UN 1309, Class 4.1 flammable solid). YANXA maintains strict compliance protocols. We use certified UN steel drums with heavy-duty plastic inner bags and nitrogen gas purging to prevent moisture absorption and ignition hazards.
To ensure smooth customs clearance and import compliance, we provide full supporting documentation for every shipment, including Certificates of Analysis (CoA), Safety Data Sheets (SDS), Certificates of Origin, and Marine Pollutant declarations.
As additive manufacturing and green chemistry evolve, YANXA is investing in next-generation material research. Our current development pipeline focuses on:
