At OKAYAMA GIKEN (Mining) Co., LTD., is a reliable Brown Fused Alumina for Abrasives manufacturer and exporter in China.Brown fused alumina (BFA), also known as brown aluminum oxide, is a durable and sharp-edged abrasive material widely used in the manufacturing of grinding wheels, sandpaper, and blasting media. As a leading Chinese manufacturer and exporter, we supply a full range of BFA products for abrasive applications worldwide with best price.
Brown fused alumina for abrasives is a key material in the abrasive industry. Its excellent hardness and toughness make it suitable for various grinding and cutting applications. it's commonly used to manufacture grinding wheels for machining steel, cast iron, and non-ferrous metals.
Brown fused alumina for abrasives are also applied in sandpaper and abrasive belts, providing effective surface finishing for automotive components, metalwork, and wooden furniture. Moreover, in the process of deburring and surface preparation, BFA for blasting media helps to remove rust, paint, and impurities efficiently.
Our brown corundum is usually used for abrasives, organic abrasives, coatings, etc.
