Brown Fused Alumina (BFA) is a very hard, tough abrasive raw material produced by melting bauxite (an aluminum ore) at extremely high temperatures. During the melting process, crystalline grains of alumina are formed, which are crushed and sieved after cooling. BFA is characterized by its brown color and it is widely used in various industrial applications due to its hardness and abrasion resistance.
