Semi-brittle corundum is a new type of abrasive developed and produced by Ruishi to meet the needs of the international market. Because its brittleness and toughness are between white and brown corundum, it is called semi-brittle corundum. Semi-brittle corundum has the advantages of high temperature resistance, corrosion resistance, erosion resistance, low porosity, and stable thermal properties. The abrasive grains have good self-sharpness, and they are sharp and difficult to burn the workpiece. After the semi-brittle corundum abrasive grains are post-processed, the relative wear resistance is increased.
Particularly suitable for the grinding of heat-sensitive steels and alloys, non-ferrous metal materials with low hardness such as aluminum, copper, zinc, lead and non-metal materials such as wood and plastic. Widely used in the production of consolidated abrasives.

Semi-brittle corundum is made of high-quality bauxite, based on the smelting of sub-white corundum, after adjusting the smelting process and proportion, it is smelted in an electric arc furnace at a high temperature of 2100 ° C and above, using a special crushing process.
