White Aluminum Oxide  Introduction:

White Aluminum Oxide  belongs to electro-corundum. It is also be called white aluminum oxide, white corundum or white fused aluminum oxide. White Aluminum Oxide  is made of aluminum oxide powder. The raw material of white Aluminum Oxide  is melted in an electric arc furnace at high temperature. White Aluminum Oxide  is not only advanced abrasives materials but also is senior grinding, polishing materials, the abrasive made of it is suitable for grinding high carbon steel, high-speed steel, and stainless steel. White Aluminum Oxide  is also widely used in precision casting, steel fire-resistant, fire-resistant chemical, porcelain, decorative porcelain and other special ceramics and porcelain in daily life, military, electronics and other high-tech industries. White Aluminum Oxide  has characteristics of white color, high hardness, low toughness, high purity, excellent self-sharpening, grinding power, heat small, high efficiency, acid corrosion, high temperature, good thermal stability.
