Brown Fused Alumina (BFA) – High-Performance Abrasive
Brown Fused Alumina abrasive, also known as brown aluminum oxide, is a high-hardness blasting media produced by the fusion of premium-grade bauxite in an electric arc furnace at over 2000°C. Moreover, it offers outstanding toughness, abrasion resistance, and thermal conductivity. As a result, it is widely applied in rust removal, sandblasting, bonded abrasives, and anti-slip flooring. In fact, its aggressive cutting performance and durability make it a reliable choice for demanding industrial surface treatment tasks.
Key Advantages of Brown Fused Alumina
High Efficiency: Small particles accelerate airflow velocity, while angular grains deliver strong impact force. Consequently, blasting and grinding become faster and more effective.
Low Consumption: More efficient than garnet; it achieves results with less material. Therefore, projects save cost and reduce waste.
Low Dust Generation: High specific gravity minimizes airborne dust. Furthermore, it enhances workplace cleanliness and operator safety.
