White Aluminum Oxide, HS Code 28181090, CAS No. 1344-28-1, which belongs to a kind of artificial abrasive. It is made of high-quality aluminum oxide powder as raw material. After being cooled and solidified in a fixed furnace/dumping furnace by high-temperature smelting, it is crushed and shaped by a crusher, and after magnetic separation, sieved into various different particle size models of white fused alumina section sand and fine powder. The content of AL2O3 in the white aluminum oxide is above 99.5%, and the hardness is relatively high. At the same time, the white aluminum oxide section sand and fine powder have the characteristics of high temperature resistance and good thermal stability.Therefore, it can be used as a furnace refractory material.

White Aluminum Oxide Application Area:
1.Metal sandblasting surface treatment: Removing the oxide layer of metal, stainless steel, aluminum alloy, tungsten molybdenum, copper products and other materials. Abrasive sandblasting to remove rust. White aluminum oxide grain has strong grinding ability and high efficiency. It can be recycled and will not leave residues on the surface of the workpiece. White aluminum oxide grain does not contain iron, sulfur, chlorine and other elements. It can be used in dentistry, food, medical equipment, aerospace and other fields : Surface treatment before spraying for spraying, painting, supersonic thermal spraying, etc., to increase the unevenness of the surface of the material and enhance the holding power of the sprayed material. B-Prepare the surface treatment before painting the back panels of mobile phones and laptops. ii.-Surface treatment before metal spray welding and titanium plating, such as sandblasting on the surface before brazing of super-hard grinding wheel and cemented carbide.
2.Surface treatment of glass and non-metallic materials: Colored glass, glass products, ceramic products, bamboo chips, wood products, composite non-metallic materials and other materials such as sandblasting, matting, polishing, matte treatment, etc. Rubber materials such as printing rubber rollers, rubber molds, PU materials, acrylic sheets, plastics and other materials are surface-etched.
3. Semiconductor industry:
White aluminum oxide used for surface treatment of aluminum alloy semiconductor components, surface treatment and sandblasting before vacuum sputtering; removal of impurities on the back of wafers.
4. Mold processing industry:
White aluminum oxide blasting media for surface treatment of metal molds, forged steel molds, forged aluminum molds, mold steel, carbon steel, and mold processing industries such as matte surface treatment after mold biting. For example, wire cutting molds, glass molds, tire molds, conductive rubber molds, shoe molds, bakelite molds, electroplating molds, button molds.
