Corundum is suitable for processing steel and silicon carbide is suitable for processing non-ferrous metals and non-metallic materials.
Brown corundum is the most common and most widely used type of abrasive in ordinary abrasives. Brown corundum has a slightly lower hardness among ordinary abrasives. However, in the grinding process, the abrasive particles have good anti-crushing performance and are suitable for grinding and processing metals with high tensile strength, such as rough grinding and heavy grinding of common steel materials, and are particularly suitable for carbon steel and general Alloy steel can also be used for grinding of cast-iron and hard bronze.[Brown Fused Alumina]
White corundum is another basic variety in ordinary abrasives. Its hardness is slightly higher than brown corundum. During grinding, the grinding effect during grinding is good and the cutting force is strong. White corundum is suitable for grinding harder steels. Such as high-carbon steel, high-speed steel, hardened steel, etc., is also suitable for easy to burn the workpiece processing, such as cutting tools, thin-walled workpiece grinding and alloy steel grinding and so on.[White alumina]
monocrystal corundum has good multi-edge cutting edge, high hardness, high toughness value, strong grinding force, small grinding heat, long abrasive cutting life, and can process hard and tough steel such as stainless steel, high vanadium high speed Steel, etc., are also particularly suitable for grinding and large-feed grinding of deformed and easily burned workpieces.[Monocrystal]
Microcrystalline corundum crystal size is small, high strength, self-sharpening, and can be used for deep grinding. In the grinding process, the microcrystalline corundum abrasive presents a micro-fragmentation state and a good self-sharpening property, so it is suitable for a heavy-duty jogging grinding.[Microcrystaline]
