Plate-like reinforced crystalline microstructureSG Abrasives – Blue Ceramic Alumina  (BCA) is a sintered polycrystalline abrasive prepared using a special alumina-containing material as the main raw material using the Sol-Gel process. It can be used in bonded abrasives and coated abrasives, and in ultra It is used to a certain extent in hard abrasive tools. Ceramic microcrystalline corundum has a unique microstructure, high hardness, high toughness, good self-sharpening, fast cutting speed during grinding, long grinding life, not easy to burn the workpiece, and low energy consumption. When grinding, due to its own sharp and angular structure, it constantly breaks to form sharp points. Each abrasive grain is ground or polished with its crystal micro-edge, self-sharpening with its crystal grains, and maintaining the sharpness of each abrasive grain. Sharpness. It has the characteristics of high hardness, good toughness, sharp grinding, and low heat generation. Especially suitable for grinding various alloy steel, quenched steel, tool steel, hard chromium, hard cast iron, and other materials.

Black Silicon Carbide 

Black silicon carbide is a widely used abrasive product, with excellent wear resistance, high hardness, high density, low impurities and other advantages, commonly used in sandblasting grinding, polishing, free grinding, making various abrasives, etc.

Black Silicon Carbide
Green Silicon Carbide

Green Silicon Carbide

Green silicon carbide is made from quartz sand and petroleum coke refined in a resistance furnace, due to its relatively stable chemical properties, high thermal conductivity, low coefficient of thermal expansion, and good wear resistance.
