Product Description

Product Description:


White corundum is an industrial material made from alumina powder that has been fused in an arc furnace. This process exposes the powder to extremely high temperatures, exceeding 2000 degrees Celsius, before it is cooled and shaped into its final form. The resulting material is then subjected to magnetic separation and particle size screening, which produces various products.


White corundum is an excellent material for the manufacture of ceramics, resin consolidation abrasive tools, and for polishing, sandblasting, precision casting, and the production of high-grade refractory materials. Its close texture, angular shape, and high hardness make it ideal for applications that require precision and accuracy.


Compared to brown corundum, white corundum has a slightly higher hardness and a slightly lower toughness. It exhibits high purity, good self-sharpening, strong grinding ability, low heat generation, high efficiency, acid and alkali corrosion resistance, and high temperature thermal stability. Additionally, it does not affect the color of the workpiece, making it an ideal material for use in polishing.


White corundum is especially useful in processes where iron powder residue is prohibited. It has a low iron oxide content, making it ideal for sandblasting operations that require no residue. Its micro-powder form is also very useful in wet sandblasting and grinding operations, as it can achieve a high processing speed and quality.




White corundum abrasive is an excellent choice for high-end products, hardware products surface beautification treatment, and various processes. Its superior properties make it ideal for achieving a polished surface finish. It is an effective solution for the following purposes:

Iron workpiece: White corundum abrasive can be used to derust, remove oxidation skin, and increase the adhesion of the coating.


Aluminum workpiece: It can remove the oxidation skin, strengthen the surface, and create a glossy effect.


Copper workpiece: White corundum abrasive can be used to remove oxidation skin to achieve a matte effect.


White corundum abrasive can be used for solid coated abrasive tools, wetting or dry sand blasting. It is effective for super fine grinding, polishing, and making high-grade refractory materials for the crystal and electronic industry.
