BFA Ceramic Coated
BFA Ceramic Coated
Description
Kowa’s Ceramic Coated BFA is a new type of abrasive made by deep processing high-quality BFA or high-temperature treated BFA as raw materials, heating at high temperature, and coating a layer of iron oxide on the surface of the grits. The product has the characteristics of large specific surface area, strong hydrophilicity, uniform particle size, high purity, strong adhesion, high grinding and cutting efficiency, and good heat dissipation performance. Its main performance indicators are as follows: compared with ordinary brown corundum, the micro hardness is increased by 10%, the toughness is increased by 10%, the hydrophilicity is increased by 3.5 times, the cutting amount is increased by 3%, and the efficiency is increased by 30-50%.
Applications
Ceramic-Coated BFA: Primary applications: coated and bonded abrasives.
Ceramic-Coated Blue-Fired BFA: Primary application: coated and bonded abrasives, especially those for use on hardened steel and other high-carbide materials.
