High quality white aluminum oxide 70 grit
Product Introduction of High quality white aluminum oxide 70 grit
High quality white aluminum oxide 70 grit is an excellent blasting media on steel, stainless steel, plastic, and iron alloy. White alox grit is very hard grinding material as an aggressive abrasive grain. It is made of 99% aluminum oxide powder as raw material, which is refined and crystallized by electric melting (thus white corundum is also called fused alumina and white fused alumina).

Low Na2O content and high Al2O3 purity.
Applications of High quality white aluminum oxide 70 grit
- 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 a 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.
- 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.
- 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.
- 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.
- 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, plastic product molds, and other molds all use alumina sand.
- Skin cleaning: Microdermabrasion Crystals with white aluminum oxide could improve scars, blackheads, and pore size. It makes skin smooth and clean without any contaminants.
