Sand Blasting Black Fused Alumina

Black Fused Alumina / Black Aluminium Oxide /BFA is in the electric arc furnace, bauxite smelting in a prepared α- Al2O3 spinel and iron ore mainly gray-black crystal phase, which is characterized by a lower Al2O3 content and a certain amount of Fe2O3 (10%) exists, which has a moderate hardness, high toughness, high temperature, thermal performance characteristics of a given temperature. More for free grinding, grinding work such as coarse grinding before electroplating products, mainly for stainless steel, metal products, optical glass, bamboo products, polishing and sand blasting, and manufacturing resin grinding wheel, cutting disc, novel abrasive emery cloth.
