Technical Specifications
Product Overview
High-Performance Brown Fused Alumina
Brown Fused Alumina (BFA) is a high-purity abrasive material produced by fusing bauxite in an electric arc furnace. Renowned for its exceptional hardness, toughness, and wear resistance, this material is ideal for demanding industrial applications including sandblasting, grinding, polishing, and lapping. Its angular grain shape ensures aggressive cutting action, while its chemical inertness and thermal stability provide reliable performance in both wet and dry processes.
