1. Brown corundum is suitable for processing steel, for glass sandblasting, metal casting and building floors. In ordinary abrasives, the hardness of brown corundum is slightly lower. However, in the working process, the abrasive grains have good crush resistance, and are suitable for processing metals with high tensile strength, especially carbon steel and general alloy steel.
2. White corundum is another basic variety in ordinary abrasives. Its hardness is slightly higher than that of brown corundum. White corundum is suitable for grinding steel with higher hardness. Such as high carbon steel, high speed steel, hardened steel, etc.
3. Single crystal corundum has a good multi-edge cutting edge, high hardness, high toughness value, strong strength, low heat, long abrasive cutting life, and can process hard and tough steel, such as stainless steel, high vanadium high-speed steel, etc. .
4. Microcrystalline corundum has small crystal size, high strength and good self-sharpening. In the working process, the microcrystalline corundum abrasive is in a micro-broken state and has good self-sharpening, so it is suitable for heavy-duty slow-feed grinding with large depths. Chrome corundum is rose-colored, so some people call it rose-colored corundum. It has moderate brittleness and good cutting performance, and is suitable for various surface processing with high smoothness.
5. Zirconium corundum has high strength, good wear resistance, high work efficiency, and the surface of the grinding wheel is not easy to block. It is suitable for heat-resistant alloy steel, titanium alloy, high-speed high-vanadium and other materials.
6. Silicon carbide is suitable for processing non-ferrous metals and non-metallic materials. Black silicon carbide is mostly used for grinding or cutting materials with low strength, such as cast iron workpieces, non-ferrous metals, abrasive tool manufacturing, and also for the processing of non-metallic materials such as stone.
7. Green silicon carbide is mostly used for materials with high hardness and brittleness; such as cemented carbide, optical glass, etc. for grinding.
