Home / Products / Brown Fused Alumina / 1350 Calcined Brown Fused Alumina For Coated Abrasives
1350 Calcined Brown Fused Alumina (BFA) is a premium abrasive material created by calcining high-quality brown fused alumina at 1350°C. This process enhances the material's toughness, thermal stability, and adhesion properties, making it an excellent choice for producing high-performance coated abrasives.
According to the calcined temperature, 1350 calcined brown fused alumina grains are calcined to blue with maximum toughness and durability. These grains have high capillarity for instant adhesion to resin or glue bonds, most of performance index is better than 1050 calcined brown fused alumina grains.
Sanding belts: P60, P80 grit abrasives can be made into sanding belts for electric or pneumatic tools; coarse grit heavy-duty sanding belts
Impeller cloth: P40, P50 grit abrasives can be made into calcined louver blades
High-grade sandpaper: P50-P150 grit abrasives can be made into high-grade sheet sandpaper and disc sandpaper
Nylon wheel: P60-P150 grit abrasives
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.
GRITS AVAILABLE：P12-P1500
