Caractéristiques

• High Hardness
  Brown fused alumina is known for its high hardness, which makes it an excellent abrasive material. Its hardness is due to the strong covalent bonds between the aluminum and oxygen atoms in the aluminum oxide crystals.
• High Strength
  Brown fused alumina has high strength, making it suitable for use in applications that require a robust and durable material. Its strength is primarily attributed to its dense, crystalline structure.
• Stabilité chimique
  Brown fused alumina is chemically stable and resistant to most acids and alkalis, making it suitable for use in corrosive environments. This chemical stability is due to the strong chemical bonds within the aluminum oxide structure.
• Heat Resistance
  Brown fused alumina has excellent heat resistance, which means it can withstand high temperatures without losing its physical properties. This heat resistance makes it suitable for use in high-temperature applications such as refractory materials and high-performance abrasives.
• Grades
  Brown fused alumina is available in various grades, which are determined by the purity of the material and the type of impurities present. The grading system is essential for categorizing the product based on its quality and suitability for specific applications.
• Grit Size Selection
  Grit size is a critical factor in determining the performance of brown fused alumina in different applications. The size of the grit is usually specified by a number, with higher numbers indicating smaller grit sizes. The selection of the appropriate grit size depends on the desired surface finish and material removal rate.

Applications

• Abrasifs
  One of the primary applications of brown fused alumina is in the manufacturing of abrasive products such as grinding wheels, papier de verre, and blasting media. Its high hardness and strength make it an excellent choice for cutting, grinding, and polishing various materials, y compris les métaux, céramique, et du verre.
• Réfractaires
  Brown fused alumina is also widely used as a refractory material, particularly in the production of high-temperature-resistant products such as bricks, castables, and monolithic linings. Its excellent heat resistance and chemical stability make it suitable for use in furnaces, fours, et autres applications à haute température.
• Surface Treatment
  Brown fused alumina is used in surface treatment processes such as shot blasting, sandblasting, and surface polishing. Its hardness and abrasiveness make it ideal for cleaning and preparing metal surfaces before painting, welding, or other operations.
• Other Applications
  Brown fused alumina has other niche applications, including the manufacturing of wear-resistant ceramics, anti-skid materials, and specialized grinding tools.
