Uncoated Aluminum Powder Suppliers - Premium Spherical Aluminum Powder from China Factory for Metal Matrix Composites

As one of the leading China suppliers of premium spherical aluminum powder, TJWX boasts over two decades of expertise in manufacturing high-quality products. Our uncoated spherical aluminum powder, featuring a distinctive silver-gray coloration, is produced from pure aluminum ingots (Al >99.8%). Utilizing a state-of-the-art high-temperature, high-pressure melting process, we ensure our aluminum powder is lightweight and efficient, significantly reducing oil consumption. This advanced manufacturing technique provides exceptional thermal conductivity, mechanical strength, wear resistance, and long-term chemical stability. Trust TJWX, your reliable factory partner in sourcing top-tier aluminum powder.

    After atomization, the spherical aluminum powder has a thick layer of alumina in its surface to keep high active aluminum inside.

    It was collected by sealing atomization, classification, blending and sieving process. During the production process, it is controlled by strict controlling method to keep the particle size distribution and consistent appearance; The particle size of spherical aluminum powder used for aluminum powder is narrow, which ensures good reflectivity, good brightness and hiding power.
