White Fused Alumina(WA),also called White Fused Aluminium Oxide, named by its white color, belongs to the electro fused artificial corundum group and is an important mineral used widely for refractory bricks,refractory castables,pre-cast refractory shapes,other unshaped refractory products,ceramic shapes,metal&ceramic surface preparation,grinding wheels,sandpapers,sanding belts,sandblasting media,lapping and polishing. It's obtained from reduced fusion of high purity calcined alumina in electric arc furnaces. Calcined alumina is the most important material in aluminium making industry. After the fusion process, the materials become liquid, then cooled down and crushed into different sizes for different applications. Magnetic contents are removed and materials are reshaped by relevant equipments, and then sieved into standard sizes(FEPA,JIS,ANSI) of standard particle distribution. It is characterized by high purity (Al2O3 content≥99%), great self-sharpening, acid and alkali resistance, high temperature resistance and stable thermal performance, which make it to be prefect raw material for all kinds of abrasive tools, including grinding high carbon steel, high speed steel, stainless steel and other fine-grained abrasives, it also can be used for precision casting and high-refractory materials.
