Soft metals lapping powder aluminum oxide powder f400 f600
Wfa with the eye-catching white color and the advantage of high density and low micro porosity, it can effectively improve the volume stability and the thermal shock resistance of the material. It is the mainly raw material to produce middle or high level unshaped or shaped refractory material. It is applied to the unshaped refractory materials, such as refractory carstables for ladles, middle or high level iron runner casting material, gunning refractory and fabricate parts ect. It also can be used to kinds of corundum products, such as corundum bricks, corundum, mullite corundum, refining corundum perforated bricks, overall blowtorch and combined nozzle, side ceiling of the high temperature kiln, ect. All in all, it is widely used in steel, cement, ceramics, grinding material and petrochemical industries.
Aluminum oxide is used successfully for cleaning, deburring, surface finishing, rust removal and old paint coatings, preparing surfaces for subsequent anti-corrosion treatments with paint and primer at the highest quality standards.

Applications of White Fused Alumina
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 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.
