Product Description

Product Description:


White corundum is a type of abrasive material that is manufactured using industrial alumina powder. This powder is melted in an arc furnace at a temperature exceeding 2000 degrees and then cooled. After being shaped and ground, the materials are then screened to ensure that they meet the desired product requirements.


Due to its close texture and angular shape, white corundum is considered a highly durable material that is suitable for a wide range of applications. It is commonly used in the manufacture of ceramics, high-grade refractory materials, and precision casting.


White corundum is known for its toughness, excellent self-sharpening ability, and strong grinding power. It is highly efficient and has a small heat output, as well as being highly resistant to acid and alkali corrosion. Additionally, it has high temperature thermal stability and does not impact the color of the workpiece, making it ideal for use in sandblasting operations where iron powder residue is not permitted.


White corundum has a slightly higher hardness than brown corundum but is slightly less tough. Its micro-powder grade is ideal for wet sandblasting and grinding operations, offering high processing speeds and quality results. Furthermore, the low amount of iron oxide in white corundum makes it suitable for sandblasting operations where no iron residue is desired.



White corundum abrasive is a versatile material that is suitable for a wide range of applications. Its main use is in high-end products and hardware surface finishing, where it is used to beautify the surfaces of composite materials and various metal products. For iron workpieces, it is particularly effective in derusting, decontamination, and removing oxidation skin, which helps to increase the adhesion of any coating applied to the surface.


For aluminum workpieces, the abrasive is useful in removing oxidation skin and enhancing surface strength, as well as creating an attractive glossy effect. For copper workpieces, the material has been shown to be effective in achieving a matte surface finish by removing oxidation skin.


The abrasive can be used in various forms, including solid coated abrasive tools, wetting or dry sandblasting. It is also useful for super fine grinding, polishing, and in the production of high-grade refractory materials, which are widely used in the crystal and electronics industry.

Moreover, the abrasive is versatile enough to be used for other purposes, such as crystal frosting of glass products, matte effect of engraved plastic products, plush processing, and effect pattern of denim and other special fabrics.
