Product Description

Longer Service Life Boron Carbide Venturi B4C Nozzle for Sandblasting, Hot-Pressed Sintering Boron Carbide Nozzles Made of High Purity B4c Micron Powders


Material: Boron Carbide (B₄C).
Jacket: Aluminum / Polyurethane Protector.

The hardness of boron carbide is only secondary to diamond and CBN. The density of the boron carbide products produced by us is close to its academic density 2.52g/cm³. The advantages are: longer service life, high hardness, high wear-resistance ability, anti-corrosion,  lower cost per use, reducing down time. It's the ideal material for sandblasting nozzle and mechanical seal.

The gas dynamics of venturi nozzle is better than straight-hole nozzle, the vortex is improved or ceased to exist, greatly reduced the pressure loss in the same pressure conditions. Abrasive exports increased to more than double the speed, efficiency than the straight-hole nozzle to increase 15% -40%, 20% lower abrasive consumption.

Boron carbide can be used to manufacture sandblasting gun nozzles, which is extremely hard and wear-resistant, no reaction with acid-base, high/low temperature resistance, high pressure resistance, crystal system: hexagonal, density: 2.52g/cm3, Mohs hardness: 9.36, microhardness 5400-6300kg/mm2, bending strength ≥400Mpa, melting point: 2450ºC. Because it has the characteristics of wear resistance and high hardness, Boron Carbide Sandblasting Nozzle will gradually replace the known carbide/tungsten steel and silicon carbide, silicon nitride, alumina, zirconia and other materials sandblasting nozzle in the future.
