Brown Fused Alumina For Sandblasting Suppliers and Manufacturers

Grains :F 36 46 60 80 70 100 120 Al2O3:95% min Brown fused alumina (BFA) is a type of synthetic abrasive which is made by fusing bauxite, iron oxide and coke at high temperatures in an electric arc furnace. It has a brown color and is used for grinding, polishing, blasting and cutting applications. BFA is known for its high hardness, toughness, and resistance to wear and corrosion. It is also chemically stable and does not react with acids or alkalis. These properties make it a popular abrasive for metalworking, surface preparation, and refractory applications. BFA is available in a range of grit sizes and can be used for both wet and dry blasting. It is commonly used for cleaning and preparing surfaces for painting or coating, removing rust and scale, and shaping and finishing metal parts. In addition to its abrasive properties, BFA is also used as a refractory material in the production of ceramics, glass, and cement. It is also used as a filler in plastics, rubber, and other composites. Package:25kg/bag,1000kg/jumbo bag

Brief introduction of brown fused alumina powder Brown fused alumina uses bauxite, coke as the main raw material, smelting in the electric arc furnace at high temperature. The composition of brown corundum mainly include AL2O3, TiO2, also contains a small amount of SiO2 and Fe2O3, micro hardness is HV1800-2200. The toughness is lower than silicon carbide, higher than that of white corundum, hardness is 9.0, slightly lower than the same level of white fused alumina. Commonly used brown fused alumina can be divided into brown fused alumina powder, brown fused alumina segment of sand,brown fused alumina granular sand. Today, I mainly explain the brown fused alumina powder related knowledge for you. Brown fused alumina powder specifications: Commonly used brown fused alumina powder specifications: 325,400,600,800,1000. . . . (Head) Gongyi Qingyun Refractories Co., Ltd. can adjust production according to customer requirements? brown fused alumina powder brown fused alumina powder Properties of brown Alumina powder The brown fused alumina powder has moderate hardness, high toughness, good self-sharpening ability, low sand consumption and recyclable use, good abrasion and abrasion resistance, and chemical composition stability, abrasion resistance, acid and alkali resistance. Especially its high hardness, specific gravity large, chemical stability and its unique self-sharpening, etc., so used as the first choice in brown fused alumina abrasive sandblasting process , but also the best choice for cleaning up the work piece. Abrasives made of brown fused alumina powder , suitable for processing a variety of general steel, malleable iron, hard bronze, etc., can also produce high-grade refractories. Brown fused alumina abrasive use high-quality brown fused alumina as raw materials, using modern new unique technology from refining.Brown fused alumina sandblasting has characteristics of short grinding time, high efficiency, good efficiency and low price. The abrasive shell-shaped fracture, sharp edges and corners, in the crushing classification in the formation of new edges and edges, so that the grinding ability is better than other abrasives.
