Heated & Ceramic Coated Brown Fused Alumina

It is ceramic coated with ferric oxide on the surface by a specific processing. It is made from high quality brown fused alumina calcined at high temperature through intensive deep processing. The product features a large specific surface area, stronger hydrophilicity, even particle size ,higher purity, stronger binding power ,cutting effciency and good heat dispersion performance , it is main performance indexes are as below: compared with normal BFA, BFA-HCC micro-hardness increases 10% ,toughness increases 10%, hydrophilicity increase 3.5 times , grinding and cutting quantity increases 3% and efficiency increase 30%-50% . It is suitable for making Top grade coated abrasive and Top grade resin bonded wheels.

Comparison of physical performance: Normal BFA and BFA-HCC

Standard： 

A- F (Bonded abrasives) F12-F220
