- Product Introduction
Products Description
Brown Fused Alumina (BFA) 80# is a high-performance abrasive material produced by smelting premium bauxite, anthracite, and iron filings in an electric arc furnace at extreme temperatures. With an Al₂O₃ content of 95-97%, it delivers exceptional durability and efficiency, while trace elements like Fe, Si, and Ti enhance its structural integrity.
This robust material excels in high-temperature and corrosive environments, making it a top choice for refractory linings in steel mills, cement kilns, and glass manufacturing furnaces. Its chemical resistance also ensures reliable performance in harsh industrial settings.
Thanks to its superior hardness and sharp-edged grain structure, Brown Fused Alumina 80# is widely used in sandblasting, surface preparation, and precision grinding. It provides fast cutting action, consistent particle size, and long-lasting performance, making it indispensable in metalworking, automotive, and heavy machinery industries.
