Brown Fused Alumina for Abrasive Tools
Brown fused alumina is made from bauxite as the main raw material and is melted at high temperature. It is brownish brown, with high hardness and toughness. The grinding tools manufactured with it are suitable for grinding carbon steel, malleable cast iron, hard bronze, etc. In addition, it is widely used in refractory materials, chemical additives, precision casting, and anti-skid materials.
Descrição: __________
We provide all specification of white fused alumina, pink fused alumina and brown fused alumina and can customize products according to your requirements. Welcome consulting.
Brown fused alumina (BFA) is a high-quality synthetic abrasive material made from the fusion of bauxite and other materials in an electric arc furnace at high temperatures. It is one of the most widely used abrasives due to its excellent grinding and cutting properties.
Brown fused alumina has a deep brown color and its unique crystal structure gives it high toughness, durability, and resistance to wear and tear. It is widely used in the manufacturing of abrasive tools, grinding wheels, sandpaper, and other abrasive products.

Application
Metal processing
Brown fused alumina abrasive can be used for grinding, polishing, and finishing of metals, such as steel, cast iron, aluminum alloys, etc. In the metal processing process, it can remove surface oxide scale, scratches, and burrs, improve the quality and smoothness of the metal surface, and provide a good foundation for subsequent treatment.
Ceramic manufacturing
Brown fused alumina abrasive is used in ceramic manufacturing to grind and polish ceramic products, such as ceramic tiles and ceramic bathroom equipment. It can remove defects and burrs on the surface of ceramics, improve the smoothness and appearance quality of ceramic products.
Precision machining
In the field of precision machining, Brown fused alumina abrasives can be used for processing and polishing precision components. Due to its high hardness, high-precision machining of precision components can be achieved, improving the dimensional accuracy and surface quality of the parts.
Grinding tool manufacturing
Brown corundum abrasive can also be used for the production of grinding tools, such as grinding wheels, abrasive belts, etc. It can provide high cutting force and grinding effect, making the grinding process more efficient and accurate.
