Product Description

Brown Fused Alumina (BFA) is an artificial corundum produced by smelting high-quality bauxite in an electric arc furnace at high temperature, followed by cooling, crushing, magnetic separation and sieving. With alumina (Al₂O₃) as the main component, it features high hardness, good toughness, and excellent wear resistance. Brown Fused Alumina is one of the most widely used abrasives and refractory raw materials in the industrial field.

Core Features

• High hardness and toughness: Mohs hardness 9, suitable for grinding and blasting of hard metals and alloys.

  
  

• Excellent wear resistance: Long service life in abrasive and blasting applications.

  
  

• Thermal stability: Strong resistance to high temperatures, widely used in refractory products.

  
  

• Versatile particle size distribution: Available in a wide range of grit and powder sizes to meet customer requirements.
