Home / Products / Brown Fused Alumina / 1350 Calcined Brown Fused Alumina For Coated Abrasives
At DOMILL, we specialize in manufacturing 1350°C Calcined Brown Fused Alumina (BFA)—a premium abrasive material designed specifically for coated abrasives, including sandpaper, sanding belts, and flap discs. Our advanced calcination process enhances toughness, stability, and cutting efficiency, making it an excellent choice for high-performance coated abrasives.
1350°C Calcined Brown Fused Alumina is produced by heat-treating standard BFA at 1350°C in a high-temperature kiln. This process removes volatile impurities, reduces internal stress, and improves the grain’s toughness and hydrophilicity.
Sanding belts: P60, P80 grit abrasive grains can be made into sanding belts for electric or pneumatic tools; coarse grit heavy-duty sanding belts
Impeller cloth: P40, P50 grit abrasive grains can be made into calcined louver blades
High-grade sandpaper: P50-P150 grit abrasive grains can be made into high-grade sheet sandpaper and disc sandpaper
Nylon wheel: P60-P150 grit abrasive grains
AB22 is sharp, low bulk density, better than AT22. The coated abrasives made of them have high sharpness, good heat dissipation effect and high durability; they are used for high-grade coated abrasives, making abrasive cloth, sandpaper, abrasive belt, processing low carbon steel, alloy steel and special wood, etc.
AB25 is angular, medium bulk density, is better than AT25. It can be used in making top-grade abrasive cloth, sandpaper, sanding belts, working on different kinds of steel, such as construction steel, alloyed steel, casting steel, nodular cast-iron, malleable cast-iron and some hard timber, etc.
DOMILL provides premium 1350°C Calcined Brown Fused Alumina to help you achieve higher efficiency, durability, and grinding performance in coated abrasives.
