China professional abrasive classification
May 30, 2018



The abrasive products are mainly divided into two categories of corundum abrasives and silicon carbide abrasives. Specifically, there are basically the following:

1. Brown fused alumina abrasive, the main component is Al2O3, with medium hardness, high toughness, sharp granules, and low price, suitable for processing high tensile metal. Microcrystalline corundum abrasives and black corundum abrasives are all derived varieties.

2, white corundum abrasive, its hardness is slightly higher than brown corundum, but the toughness is poor, easy to cut into the workpiece when grinding, self-sharpness is good, less heat, grinding ability, high efficiency. Chrome corundum abrasive is its derivative species.

3, single crystal corundum abrasive, its particles are composed of a single crystal, and has a good multi-edged cutting edge, high hardness and toughness, grinding ability, grinding heat, the disadvantage is the higher production costs, output Lower, so the price is higher. The zirconia corundum abrasive is also a crystalline compound with a slightly lower hardness, a finer crystal size and good wear resistance.

4, black silicon carbide abrasive, green silicon carbide abrasive, cubic silicon carbide abrasive, silicon carbide abrasive, etc., are silicon carbide abrasive, the main component is silicon carbide SiC, high hardness, brittleness, sharp grain, good thermal conductivity, Strong wear resistance, suitable for processing hard and brittle metal and non-metal products.
