The size, shape, hardness and friability of an abrasive particle determine its characteristics as an abrasive. Coarse, larger grains normally remove material faster than smaller grains, which usually give better surface finish.
Conventional abrasives can be silicon carbide, aluminum oxide, boron carbide, tungsten carbide, hardened steel and coated tools. Silicon carbide, also called carborundum, aluminum oxide and boron carbide, a compound of boron and carbon, are crystals used for ...
