Introduce
INTRODUCE

White corundum 2000# for powder coating increasing hardness belongs to electro-corundum. It is also be called white aluminum oxide, white corundum or white fused aluminum oxide. White fused alumina is obtained from the fusion of high purity calcined alumina in electric arc furnaces. Compared with brown fused alumina, white fused alumina is characterized with high alumina purity, high hardness, chemical stability, high melting point, and large crystal size. It is widely used in coated and bonded abrasives, polishing, precision casting, sandblasting and refractory raw materials.

Characters
White corundum 2000# for powder coating increasing hardness

High Alumina

White corundum 2000# for powder coating increasing hardness has a Aluminium Oixde(Al2O3) content of more than 99%. The high alumina content is ensured from its raw material which is calcined alumina.The high content of Al2O3 makes it perform well in fireproof and refractory applications.

Little Impurities

White corundum 2000# for powder coating increasing hardness has very little impurities, usually less than 0.4% Na2O, less than 0.15 SiO2 and less than 0.15 Fe2O3. It is chemically stable and little impurities make it ideal for refractory uses.

High Hardness

The high content of Al2O3 (Aluminum Oxide) makes it to be with very high hardness (Mosh Hardness≥9) and It’s usually utilized for grinding ,cutting, lapping, sandblasting, polishing, surface preparing and also for coated abrasive application, including sandpaper and sand belt.It’s not easy to break and good for abrasives. In abrasives industries, it is used for cutting wheels, grinding wheels etc, also used for coated abrasives applications like sandpapers. It’s white color and little impurities also make it excellent grinding and sandblasting media for preparing and polishing surface of metal, ceramic products etc. WA fines is also an good material for polishing and water jetting in electronics industry.

Sharp Edges

White corundum 2000# for powder coating increasing hardness is a crystal mineral with sharp edges and widely used in sandblasting,cutting and grinding abrasives.
