1. Black corundum is suitable for processing steel, used for glass sandblasting and hardware forging building floors. The hardness of brown corundum is slightly lower in ordinary abrasives. However, in the grinding process, its abrasive particles have better resistance to crushing, and it is suitable for grinding and processing metals with higher tensile strength, such as rough grinding and heavy grinding of ordinary steel, especially suitable for carbon steel, general Alloy steel can also be used for grinding forged cast iron and hard bronze.
2. White corundum is another basic variety in common abrasives. Its hardness is slightly higher than that of brown corundum. During grinding, the grinding effect is good and the cutting force is strong. White corundum is suitable for grinding steel with higher hardness. Such as high-carbon steel, high-speed steel, quenched steel, etc., are also suitable for the processing of workpieces that are prone to burns, such as cutting tools, grinding of thin-walled workpieces, and fine grinding of alloy steel.
3. Single crystal corundum has a good multi-edge cutting edge, high hardness, high toughness value, strong grinding force, low grinding heat, long abrasive grain cutting life, and can process harder and tougher steel, such as stainless steel, high Vanadium high-speed steel, etc., is especially suitable for grinding and high-feed grinding of deformed and easily burned workpieces.
4. Microcrystalline corundum has small crystal size, high strength, good self-sharpening, and can be used for deep grinding. In the grinding process, the microcrystalline corundum abrasive presents a micro-cracked state and has good self-sharpening properties, so it is suitable for heavy-load slow-feed grinding with a large grinding depth.
Chrome corundum is rosy, so some people call it rosy corundum. It has moderate brittleness, good cutting performance, and is suitable for various high-finish surface processing or profile grinding.
5. Zirconium corundum has high strength, commensurate wear resistance, high grinding efficiency, and the surface of the grinding wheel is not easy to be blocked. It is suitable for heavy load grinding or rough grinding of stainless steel, heat-resistant alloy steel, titanium alloy, high speed and high vanadium and other materials.
6. Silicon carbide is suitable for processing non-ferrous metals and non-metal materials. Black silicon carbide is mostly used for grinding or cutting materials with lower strength, such as cast iron workpieces, non-ferrous metals, abrasive tools, and stone and other non-metal materials.
7. Green silicon carbide is mostly used for materials with high hardness and high brittleness; such as grinding of cemented carbide and optical glass. Feizhan Abrasives produces black and green silicon carbide. The particle size sand powder is smelted in a large furnace, and the particle size number ranges from 36# to 1800#, with national standard and daily standard to 8000#. The product has high bulk density, strong grinding ability, high hardness, strong cutting ability and average particle size. It is widely suitable for ceramic grinding blocks, hardware grinding, electronics, jewelry polishing, etc. It is the best choice for friends.
