The chrome corundum produced by Qinai is made from alumina as the main raw material, mixed with chromium oxide, and smelted at high temperatures. It is pink in color, with hardness similar to white corundum but higher toughness. The abrasives made from it have excellent durability and high grinding finish, along with uniform particle size distribution and low magnetic content. It is suitable for precision grinding of measuring tools, machine tool spindles, instrument parts, threaded workpieces and other components.
