Product Overview:
Brown Fused Alumina (BFA) is made from Calcined Bauxite. It is a hard and tough material, used in manufacturing of grinding wheels (both vitrified and resin bonded) and coated products. These grains are also used for shot blasting and as polishing media. It is available in grit sizes as per FEPA for abrasive applications and group grits for refractory applications.
Advantages：
Brown Fused Alumina has the is featured by high packing density, high purity, compact texture, good self sharpening, good toughness and low magnetic content.

Application：
Abrasives
One of the primary applications of brown fused alumina is in the manufacturing of abrasive products such as grinding wheels, sandpaper, and blasting media. Its high hardness and strength make it an excellent choice for cutting, grinding, and polishing various materials, including metals, ceramics, and glass.
Refractories
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, kilns, and other high-temperature applications.
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.

The high hardness of fused alumina enables it to maintain sharp cutting edges, resist wear, and provide consistent abrasive performance, making it suitable for challenging grinding and cutting applications.
Scratches appear in the polishing process because there are large grains in the abrasive product, resulting in a poor product appearance and poor cleanliness.
Fused alumina is considered environmentally friendly compared to some other abrasive materials due to its durability, recyclability, and minimal environmental impact during production and use.
