F500 White fused alumina polishing powder

F1200 used in coating production polishing powder alumina micro powder White fused alumina

WA Abrasive grain is one of the most commonly used abrasive materials for abrasive tools. The white fused alumina F grit could be used for bonded abrasives such as cutting wheels, grinding wheels, vitrified grinding wheels, whetstones, etc. White fused alumina is made by a process of high temperature melting aluminium oxide method in a fixing furnace. It is of excellent self-sharpening property, good toughness, and aggressive grinding ability.

• Typical chemical analysis

• Product Feature

1. Excellent self-sharpening ability.
2. High hardness.
3. Easy to mix with colorant to get color wheels.
4. Good grinding ability. It will get sharp grinding of abrasive wheels.
5. High Al2O3 purity with low Na2O and low SiO2
6. Suitable for a large range of substrate including stainless steel, iron, metal, steel, etc.

• Applications 

  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 :

  i. -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:

  i. 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, plastic product molds and other molds all use alumina sand.

  5.Skin cleaning:Microdermabrasion Crystals white aluminum oxide could improve scars,blackheads,pore size. It makes skin smooth and clean without any contaminant.
