Home / Products / Brown Fused Alumina / 1050 Calcined Brown Fused Alumina For Bonded Abrasives
1050 Calcined Brown Fused Alumina (CBFA) is a specially treated abrasive material derived from high quality brown corundum. It undergoes a calcination process at 1050°C to enhance its performance by reducing internal stress, increasing toughness and increasing stability. This material is particularly suitable for producing medium quality bonded abrasives for grinding, cutting and polishing applications.
After calcination, brown fused alumina reduces the reverse expansion, impurities and micro-cracks caused by crushing of abrasive particles, and the grain has the characteristics of high purity, stable chemical properties and high temperature resistance. Its toughness, hydrophilicity, cleanliness, magnetic content and hardness are obviously higher than regular BFA.
Grinding wheels: Provide consistent grinding performance for metals (including carbon steel and alloys).
Cutting discs: Improve the sharpness and cutting accuracy of industrial-grade tools.
Polishing wheels: Achieve excellent surface finish, especially for hardened materials.
Resin and ceramic binders: ensure a strong bond, improve the durability and heat resistance of abrasive tools.
AT12 is sharp, low bulk density, better than A12. AT12 is suitable for making mid-range resin bonded abrasives, with fast cutting and high grinding ratio, machining of low carbon steel, steel alloy, hard bronze and rubber.
AT18 is blocky, high bulk density, better than A18. The abrasive tools made by them have improved durability, is suitable to make mid-range bonded abrasives for heavy-duty machining, cylindrical grinding and malleable cast-iron.
