Product Description

Product Description:

White corundum is manufactured using industrial alumina powder. The powder is melted in an arc furnace at extremely high temperatures of 2000 degrees Celsius or higher, then cooled, ground, and shaped. Magnetic separation of iron and particle size screening is conducted to create different product grades.


The resulting white corundum is highly valued due to its close texture, angular shape, and high hardness, making it perfect for use in a variety of applications. It can be used in the making of ceramics, resin consolidation abrasive tools, and for grinding, polishing, and sandblasting. It is also used in precision casting, where special corundum is needed. Additionally, it can be used in the production of high-grade refractory materials.


White corundum is known for having slightly higher hardness than brown corundum, while its toughness is slightly lower. It is highly pure with excellent self-sharpening, strong grindability, high efficiency, and small heat production. It is resistant to both acid and alkali corrosion and can maintain its thermal stability even at high temperatures.


Another key advantage of white corundum is that it does not affect the color of the workpiece it is used on. It can be used for sandblasting processes where iron powder residue is prohibited. Its micro-powder grade is ideal for wet sandblasting and grinding, providing high processing speed and quality. The amount of iron oxide in white corundum is very low, making it perfect for sandblasting operations where no iron residue is desired.



White corundum abrasive is a versatile product that can be used for a variety of high-end projects, including surface beautification of process or hardware products. Its capabilities include:

  • Removing rust, dirt, and oxidation skin from iron workpieces, and increasing the adhesion of the coating
  • Removing oxidation skin from aluminum workpieces, strengthening their surfaces, and creating a glossy effect
  • Removing oxidation skin from copper workpieces to achieve a matte effect


White corundum abrasive can be used in solid coated abrasive tools, both in wet and dry sandblasting methods. Additionally, it can be used for super fine grinding, polishing, and creating high-grade refractory materials for the crystal and electronic industry.


Finally, this abrasive can be used for many other applications such as crystal frosting of glass products, matte effect of engraved plastic products, plush processing, and effect patterns of denim and other special fabrics.
