Product Description:

White corundum is made from industrial alumina powder, which is melted in arc furnace at a high temperature of more than 2000 degrees. After cooling, it is then shaped by grinding and magnetic separation of iron. Particles sizes are separated into different products.

The material has a close texture and high hardness and has an angular shape. As such, it is suitable for the manufacture of ceramics and resin-consolidated abrasive tools. Grinding, polishing, sandblasting, and precision casting (investment casting special corundum) can also benefit from the material. Furthermore, it is also utilized to create high-grade refractory materials.

Features:

Raw manufacturers have complete control over the production process, which provides many benefits. This includes being able to manage quality of products and respond quickly to any issues or changes in demand.

Additionally, cost savings can also be achieved. By producing raw materials in-house, manufacturers can avoid the markup from third-party suppliers. It can result in significant cost savings in the long run.

Technical Parameters:

White corundum is mainly composed of Al2O3, with a density of 3.95g/cm³ and Mohs hardness of 9.0. It has a tripartite crystal system, providing an overall high level of compressive and tensile strenght of 2,000 MPa and 400 MPa respectively, as well as a flexural strength of 480 MPa.

White corundum exhibits a thermal expansion coefficient of 8×10^-6 K^-1 and a thermal conductivity of 29 W/(m-K), making it suitable for application in extreme temperatures. In addition, its thermal stability is high, making it highly suitable for use at elevated temperatures.

Applications:

White corundum abrasive is an ideal material for all kinds of high-end products. It can be used for enhancing the surface of a variety of processing and hardware products.

For iron workpieces, corundum abrasive is perfect for removing rust, reducing contamination and stripping away oxidation. In addition, it can also increase the adhesion of coatings. For aluminum pieces, it can be used to strip away the oxide layer and strengthen the surface, creating a glossy effect. The same principle applies for copper, however the finished result is a matte finish.
