China Suppliers of Uncoated Aluminum Powder for Refractory Bricks - High-Quality Factory Production
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.
