Brown corundum

The outstanding feature is the small crystal size and impact resistance, due to the use of self-grinding machinesProcessing and crushing, the particles are mostly spherical particles, sharpstone brand brown corundum has the characteristics of high purity, dense texture, large bulk density, strong self-sharpening, good toughness, and low magnetic content, and the grinding tool made of it is sharp, low heating rate, high grinding ratio, and less adhesion when used; The sintered abrasives made have the characteristics of dark blue color after firing, no mesh cracks, and no rust spots, and are suitable for the manufacture of ceramics, resin high consolidation abrasives, grinding, polishing, etc.
