Product Features

Semi-brittle corundum is made from high-quality bauxite. On the basis of sub-white corundum smelting, by adjusting the smelting process and ratio, and melting at high temperature above 2000℃ in an arc furnace, it is produced through a special crushing process.

Because its brittleness and toughness are between white corundum and brown corundum, it is called semi-brittle corundum.

Key Characteristics:

• High temperature resistance

• Corrosion and erosion resistance

• Low porosity and stable thermal performance

• Abrasive grains with good self-sharpness → sharp cutting ability without burning the workpiece

• Improved abrasion resistance after further processing

Application Advantage:
Especially suitable for grinding of:

• Heat-sensitive steels and alloys

• Non-ferrous metals (aluminum, copper, zinc, lead)

• Non-metallic materials (wood, plastic)

It is also widely used in the production and manufacture of consolidated abrasives.

Our company maintains a long-term cooperation with Guizhou Dazhong Seventh Grinding Wheel Co., Ltd., who use semi-brittle corundum and calcined semi-brittle corundum as raw materials to produce a series of semi-brittle corundum micropowders.
