Application of Boron Carbide in Nozzle
In the arms industry, it can be used to manufacture gun nozzles. Boron carbide, extremely hard and wear-resistant, no reaction with acid and alkali, high/low temperature resistance, high pressure resistance, density ≥2.46g/cm3; microhardness ≥3500kgf/mm2, flexural strength ≥400Mpa, melting point 2450℃.
Because of the above characteristics of wear resistance and high hardness of boron carbide nozzles, boron carbide sandblasting nozzles will gradually replace known sandblasting nozzles of cemented carbide/tungsten steel and silicon carbide, silicon nitride, alumina, zirconia and other materials .
