Fused aluminum oxide grit is made of electrofused corundum blocks, Grits range from F8 to F220. Fused aluminum oxide grit is a basic raw material in many industries. The following applications are among the most used fields：
Abrasive sandblasting and surface treatment:
Remove the oxide layer of metal, stainless steel, aluminum alloy, tungsten molybdenum, copper products, and other materials. Fused aluminum oxide Grit has strong grinding power and high sandblasting efficiency. Fused aluminum oxide grit can be recycled and will not leave residues on the surface of the workpiece. It 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 superhard grinding wheel and cemented carbide.
The raw material of abrasive tools
Cutting discs, ceramic grinding wheels, wire drawing wheels, polishing wheels, nail strips, rubber grinding heads, rubber grinding heads, and other abrasive products.
Surface treatment of glass and non-metallic materials:
Color glass, glass products, ceramic products, bamboo, wood products, composite non-metallic materials and other materials are sandblasted, matted, polished, and matted. Rubber materials such as printing rubber rollers, rubber molds, PU materials, acrylic sheets, plastics and other materials are surface-etched.
Fused aluminum oxide grit for semiconductor industry:
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:
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.
Addition of wear-resistant materials:
Fused aluminum oxide grit has high wear resistance, high hardness, and fire resistance temperature of 1850 degrees. It can be added to composite materials as wear-resistant materials to enhance the strength and heat resistance of the material.
Unsaturated polyester resin gel coat, glass fiber reinforced plastic FRP material with wear-resistant aggregate, locomotive brake disc with friction material, polyester glass fiber reinforced plastic grating surface sand, composite wood floor wear-resistant paper additive material, epoxy artesian floor coating wear-resistant Add wear-resistant materials to aggregates and ceramic glazes.
Refractory materials, raw materials for refractory products:
manufacturing and producing white corundum crucibles, ceramic electronic components production container saggers, refractory bearing plates, and other products. It can also be used as casting surface sand for precision casting.
