Brown Fused Alumina (BFA) is a high-quality, tough, and durable abrasive material made by fusing bauxite in an electric arc furnace at high temperatures. It is mainly used in the production of abrasives, refractories, and other industrial applications where durability, hardness, and high wear resistance are crucial.

Main particle size grades：
For Abrasive:
Grain: F12-F220, P8-P220 or other sizes.
Powder: F230-F1200, P230-P2000 or other sizes.

For Refractory: 0-1mm, 1-3mm, 3-5mm or other sizes.

Applications of BFA

• Abrasives: Grinding wheels, sandpaper, and polishing compounds.
• Refractory Materials: Used in the manufacture of high-performance refractories that can withstand high temperatures in furnaces, kilns, and other thermal applications.
• Blasting Media: It is also used in shot blasting and sandblasting operations to clean and prepare surfaces.
• Precision Casting: BFA is used in the precision casting process as an investment material.
• Water Filtration: Sometimes used in water treatment systems to remove impurities.
