Ge Gangyu is the main raw material of aluminum oxide, suitable for oxidation of chromium, etc by high temperature melting. Chrome corundum is pink, hardness and white corundum, toughness is higher than white corundum. With chromium corundum made of abrasive, durable degree is good, grinding and processing high. Suitable for precision grinding, such as measuring tools, machine tools, instrument parts, thread workpieces and sample grinding.
