Brown Fused Alumina of Miiddle Temperature Calcined 1050℃
After calcinations at 1050℃,with the anneal treatment, and subsequent processing ,the organic matters inherent in the grains will vaporize and the grains more higher purity, cleanliness, better hydrophilicity, smaller expansion coefficient ,higher toughness ,lower magnetic content and higher strength , improving the grinding efficiency. It is more suitable for producing top grade coated abrasive tools and bonded abrasive tools.
A F (Bonded abrasives) F12-F220
A P (Coated abrasives) P12-P220
