Venturi Nozzle

Venturi nozzle is used for heavy duty sand blast, nozzle aperture from 5.0mm - 12.5mm.


Product Features:

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. Its advantages are: High hardness, high wear-resistance ability, anti-corrosion, lower cost per use, reducing down time.



Application Fields:

It is mainly used for sandblasting of metal and non-metallic materials. When using high hardness abrasive grain such as silicon carbide and corundum sandblasting, boron carbide nozzle is ideal.
