Sol-gel Alumina abrasive grain Ceramic Alumina grit SG Abrasive grain
SG(Sol-gel) is the ceramic alumina abrasive developed and produced by our company. It’s a composition of sub-micro aluminum oxide and lamellar grain containing rare earth materials. The grain combines unique self-sharpening properties with high hardness and toughness. Ceramic alumina is applied to kinds of bonded abrasive tools with moderate bulk density and nice particle shape. Ceramic Alumina can be used in a wide range of applications and provides the highest performance and a long tool life.
