| Application and technical parameters |
| Code | Type | Feature | Usage |
| A | Corundum | High hardness and toughness | Applicable to high tensile strength metal grinding, such as general carbon steel, alloy steel, malleable iron and hard bronze |
| WA | Fused | Hardness than corundum, abrasive easily broken, sharp edges and corners, good cutting, grinding heat and small. | Be applied in hard, strong steel grinding heat sensitive. Such as hardened steel, high carbon steel, general high speed steel, alloy steel grinding. Used tools, cutting tools, gear, thread, thin-walled parts such as grinding and grinding |
| PA | Chrome-corundum | Similar hardness and white fused alumina, white fused alumina than in the high toughness, abrasive cutting edge sharp edges and corners to keep good, high durability. | For hardened steel, alloy steel grinding tool and the workpiece and the measuring and instrumentation components such as precision grinding, also apply to grinding |
| SA | Single-crystal corundum | With brown, white fused alumina compared to high hardness, toughness, showed a single particle spherical crystal, has a good multi-row cutting edge, strong anti-crushing | For stainless steel, high speed steel, vanadium steel, high hardness, toughness and deformation, easy to burn the workpiece grinding. |
| MA | Corundum ceramics. | Particle by the tiny crystals. Toughness, high strength, self-sharpening abrasive. | Applicable bearing steel, stainless steel and special cast iron grinding. For forming mill, cut into the mill, and other precision grinding. |
| A/WA | Brown-white mixture | With brown, white fused alumina two advantages. | Applied to ductile iron crankshaft, camshaft and other parts of the grinding and other grinding. |
| GC | Green Silicon Carbide | High hardness, brittleness, abrasive sharp, good thermal conductivity. | Applicable to carbide cutting tools.Parts and non-ferrous metals, non-metallic grinding, etc. |
| C | Black silicon carbide | High hardness, brittle, abrasive sharp, has a thermal conductivity. | Non-ferrous metals and non-metallic materials suitable for grinding. |
