3. Performance characteristics
Brown corundum has moderate hardness, high toughness, good self-sharpening, low sand consumption and can be recycled and reused, and the polished parts are good; and it has stable chemical composition, wear resistance, acid and alkali resistance. The abrasive shell has a shell-shaped fracture and sharp corners, which can form new corners and edges during continuous crushing and classification, so that the grinding ability will not be weak.
Black corundum has good self-sharpening properties, low heat generation during grinding, good finish of processed parts, and good hydrophilicity.

5. Use object
Brown corundum is the use of universal abrasives, special alloys, ceramics, linings (walls and tubes) of iron-making blast furnaces; physical and chemical utensils, spark plugs, heat-resistant and oxidation-resistant coatings. Black corundum is particularly suitable for the grinding and polishing of stainless steel workpieces and the manufacture of oilstone and abrasive paste.
