Abrasive properties of black corundum
Black corundum abrasive is made of bauxite as the main raw material, adding a small amount of reducing agent, and then smelting at high temperature in an electric arc furnace. Its color is black. Moderate hardness, high toughness, sharp edge and wear-resistant, strong self-sharpening, less grinding heat, high cleanliness of polished workpieces.
Black corundum applications: can be used to polish aluminum products and stainless steel, make sandpaper, emery cloth and resin abrasive.
Abrasive properties of brown corundum
Brown corundum abrasive is made of alumina powder by electrofusion, refining and crystallization, with high purity. The main component is alumina, so it is also called brown corundum! White corundum has higher hardness and brittleness than brown corundum, and brown corundum is harder than good! Brown corundum is characterized by high hardness, brittleness, strength and toughness.
Scope of application of brown corundum: can be used for the production and processing of refractory materials, polishing and grinding of precision instruments, auxiliary raw materials for wear-resistant materials.
Black corundum grinding has its inherent sand burial properties, some black corundum grinding tools are easy to bury sand, while others are difficult to bury sand; As for black corundum grinders embedded with sand, some black corundum grinders can still be used multiple times, while others cannot be used again without a few grinders. The above examples show that the accuracy of the surface geometry of the black corundum grinding tool and the inherent sand embedding of the grinding tool will directly affect the quality and cutting ability of the workpiece. A good black corundum abrasive can guarantee grinding quality and efficiency.
