Uncoated Aluminum Powder for Refractory Bricks - China Suppliers & Factory with 20+ Years Experience
TJWX is a leading factory in China with over 20 years of experience in producing high-quality spherical aluminum powder. Our uncoated spherical aluminum powder is silver gray and manufactured from aluminum ingots (Al > 99.8%) using advanced melting techniques under high temperature and pressure. This process ensures a lightweight product with excellent reducibility due to its high active aluminum content. As reputable suppliers in the industry, we prioritize stability and safety in our production, making our spherical aluminum powder a top choice for various applications
Following the atomization process, our spherical aluminum powder develops a protective alumina surface layer, effectively preserving the material’s reactive aluminum core while maintaining exceptional stability. For technical details or customized inquiries, reach out to our experts at info@hnjwx.com.
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.
