White Alumina Oxide For Sandpaper

White Fused Alumina(WFA), also called White Fused Aluminium Oxide, named by its white color, belongs to the electro fused artificial corundum group. It's an important mineral with chemical and high temperature stability, great purity, hardness and fireproof and refractory characters. White fused alumina is one of the most widely used raw materials for so many industrial fields, including refractory, bonded abrasives and coated abrasives industries.

Introduction


White Alumina Oxide For Sandpaper is a premium white fused alumina specifically engineered for coated abrasive applications. Produced from high-purity Bayer alumina in an electric arc furnace, it features sharp, angular grains with excellent self-sharpening properties. This ensures consistent cutting action, high material removal rates, and extended sandpaper life. Its carefully controlled particle shape and surface chemistry also provide superior adhesion to resin and glue systems used in coated abrasive manufacturing.
