white fused alumina WA WFA polishing for Mobile phone shell

white fused alumina WA WFA polishing for Mobile phone shell

White fused alumina is made from high quality alumina by being melted above 2000°C in the electric arc furnace.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,etc. 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, and other fine-grained abrasives, it also can be used for precision casting and high-refractory materials.
