Abrasive classification

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

1. Brown corundum abrasive, the main component is Al2O3, with medium hardness, high toughness, sharp particles, relatively low price, suitable for processing metals with high tensile strength. Microcrystalline corundum abrasives and black corundum abrasives are its derivatives.

2. White corundum abrasive, its hardness is slightly higher than brown corundum, but its toughness is poor, it is easy to cut into the workpiece during grinding, has good self-sharpening, low heat generation, strong grinding ability and high efficiency. Chrome corundum abrasive is its derivative.

3. Single crystal corundum abrasive, its particles are composed of a single crystal, and have good multi-faceted cutting edges, high hardness and toughness, strong grinding ability, low grinding heat generation, but the disadvantage is that the production cost is high, the output is low, so the price is relatively high. Zirconium corundum abrasive is also a crystalline compound with slightly lower hardness, finer crystal size and good wear resistance.

4. Black silicon carbide abrasive, green silicon carbide abrasive, cubic silicon carbide abrasive, cerium silicon carbide abrasive, etc. are silicon carbide abrasives. The main component is silicon carbide SiC. They have high hardness, high brittleness, sharp abrasive grains, good thermal conductivity, and strong wear resistance. They are more suitable for processing hard and brittle metals and non-metallic products.
