The grinding process requires rapid removal of materials to reduce the piece worked to a specific size or removes surface damage, making Silicon Carbide an obvious choice due to its abrasive properties.
Silicon carbide abrasives tools are harder and more friable as i.e. Aluminum Oxide. These characteristics make silicon carbide abrasives ideal for grinding low tensile materials like grey iron and as well as non-metallic materials such as glass, plastic and rubber.
There are two types of Silicon carbide, black and green SiC:
