Chromium corundum is made from alumina powder as the main raw material，with an appropriate addition of chromium oxide, etc.，and is formed by high-temperature melting，appearing pink and deep red。Its hardness is similar to that of white corundum，and its toughness is higher than that of white corundum。Chromium corundum has good crystallinity、pure color、few impurities、uniform particle size composition、low magnetic material content、high bulk density、and high toughness value，and is highly praised by users at home and abroad。

It is used in the field of special high-temperature refractory materials，and its high-temperature resistance is higher than that of white corundum and brown corundum。Abrasives made from it have good durability，and deliver a high surface finish in grinding。It is suitable for precision grinding of measuring tools、machine tool spindles、instrument parts、threaded workpieces、and template grinding。

Chromium corundum materials can also be used in the coated abrasives production industry，mainly for sanding wood，and can also be used for grinding non-ferrous metals，such as copper、brass and other metals，compared with white corundum，chromium corundum is less likely to break，therefore forming a smooth surface。
