Product Description

Product Description:


White corundum is manufactured from industrial alumina powder. It starts by being melted in high temperature arc furnace that reaches over 2000 degrees Celsius, and is then cooled. After the initial process, it is grinded and shaped, and then magnetically separated from iron particles, while size screening divides it into different products.


White corundum is praised for having a close texture, as well as its high hardness and angular shape. As a result, it is ideal for making ceramics, and for resin consolidation abrasive tools, as well as for grinding, polishing, sandblasting and precision casting (investment casting special corundum). Moreover, this material is also suitable for the fabrication of high-grade refractory materials.




Raw manufacturers can have full control over their production process, which enables them to provide good quality products in a timely manner while reacting to any changes in demand swiftly.


In addition, they would be able to save costs by avoiding the extra cost associated with buying from external sources. This could, eventually, result in a great saving amount in the long run.


Technical Parameters:


Type: white corundum

Chemical composition: Al2O3

Density: 3.95g/cm³

Hardness: 9.0 Mohs hardness

Crystal structure: tripartite crystal system

Compressive strength: 2,000 MPa

Tensile strength: 400 MPa

Flexural strength: 480 MPa

Thermal expansion coefficient: 8×10^-6 K^-1

Thermal conductivity: 29 W/(m-K)

Thermal stability: high temperature stability, can withstand the use of extremely high temperatures.




White Corundum abrasive is the ideal abrasive for high-end products, processes or hardware products in need of surface beautification treatments.


It can be used to make iron workpieces have a rust-free, clean surface, completely removing oxidation layers, all the while increasing the adhesion of the coating.


It is also useful for aluminum workpieces, making the removal of oxidation layers and the strengthening of the surface easier, resulting in a smooth, glossy finish.


Finally, it is an effective tool for copper workpieces, managing to strip away oxidation layers to secure matte effect finishes.
