Chromium corundum

Chromium corundum is produced by melting aluminum oxide powder，with the addition of chromium oxide and other components，at high temperatures，resulting in a pink or deep red color。Its hardness is similar to that of white corundum，but its toughness is higher than that of white corundum.The company’s chromium corundum features excellent crystallinity、pure color、low impurity content、uniform particle size distribution、low magnetic content、high bulk density、and high toughness，and is highly praised by customers at home and abroad.

Chromium corundum is produced by melting aluminum oxide powder，with the addition of chromium oxide and other components，at high temperatures，resulting in a pink or deep red color。Its hardness is similar to that of white corundum，but its toughness is higher than that of white corundum. Chromium corundum features excellent crystallinity、pure color、low impurity content、uniform particle size distribution、low magnetic content、high bulk density、and high toughness，and is highly praised by customers 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. Abrasive tools 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 templates.

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 prone to breakage，therefore forming a smooth surface.
