Thanks to its exceptional hardness, its sharp edges and brittleness, SiC ranks alongside corundum as the main material for the production of ceramic- or synthetic-bonded abrasive wheels, papers and cloths. It is used for machining all solid materials such as hard metals, cast iron, copper, brass, aluminium, zinc, glass, marble, granite, coal, plastics and wood.
In loose form too, SiC is used to grind and cut glass, marble and granite. Silicon carbide grades are used in loose form for machining glass and for lapping metallic workpieces as well as for cutting stone blocks with cable saws. From coarse grades (several mm) down to ultrafine grades (several µm), SiC can be used in loose or bonded form.
