b4c venturi sandblasting nozzle

 The b4c venturi sandblasting nozzles are in very high hardness, excellent wear resistance and the boron carbide won’t react with acid-base.
High/low temperature resistance, high pressure resistant, density≥2.46g/cm³,micro hardness≥3500kgf/mm², TRS≥400Mpa, melting point is 2450℃.
With above performance, now many customers choose the boron carbide nozzles to replace the nozzles made from tungsten carbide, silicon carbide, silicon nitride, aluminium oxide, zirconium oxide, etc.
The density also can be made to ≥2.48g/cm³
