Brown Fused Alumina, commonly referred to as BFA, is produced by fusing high-quality bauxite in electric arc furnaces above 2000°C, features exceptional hardness, strength, and thermal properties. This material forms a dense, tough crystalline structure, primarily composed of aluminum oxide. Its consistent particle size and low iron content enhance performance, while excellent thermal conductivity makes it suitable for heat-resistant applications like refractories. Its superior abrasion resistance and durability, on the other hand, make it a key material in the abrasives industry.
