Abrasive material selection

Brown fused alumina is suitable for processing steel, and silicon carbide is suitable for processing non-ferrous metals and non-metallic materials.

Brown fused alumina is the most common and widely used abrasive in conventional abrasives. Brown fused alumina has a slightly lower hardness in ordinary abrasives. However, in the grinding process, the anti-crushing performance of the abrasive grains is better, that is, the toughness is better, and it is suitable for grinding the metal with high tensile strength, such as coarse grinding and heavy grinding of ordinary steel, especially suitable. For carbon steel, general alloy steel, it can also be used for grinding of malleable iron and hard bronze.

White corundum is another basic variety in ordinary abrasives. Its hardness is slightly higher than that of brown corundum. When grinding, it has good grinding performance and strong cutting force. White corundum is suitable for grinding high hardness steels, such as high carbon steel, high speed steel, hardened steel, etc. It is also suitable for the processing of burnt parts, such as cutting tools, grinding of thin-walled workpieces and fine grinding of alloy steel. .
