Uncoated Aluminum Powder for Refractory Bricks - High-Quality Supplier from China Factory
TJWX, a leading supplier in China, boasts over twenty years of experience in the production of high-quality spherical aluminum powder. Our state-of-the-art factory ensures that all products are manufactured with stability and safety, Our uncoated spherical aluminum powder is characterized by its striking silver-gray appearance and is derived from aluminum ingots (Al > 99.8%) processed through our advanced melting furnace under high temperature and pressure. This innovative production method not only results in lightweight materials but also enhances the powder's reducibility due to its high active aluminum content. Choose TJWX for reliable and effective spherical aluminum powder solutions
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.
