Boron Carbide Venturi Nozzle 5.5 mm

Why Boron Carbide for Blasting Nozzles

Boron carbide is one of the hardest materials available for blasting nozzles, second only to diamond. In venturi nozzle designs, the material's extreme hardness translates to superior resistance to abrasive wear, maintaining the critical internal geometry for longer. This means consistent blast velocity and pattern over the nozzle's life, reducing the frequency of replacements and the labor cost of changeovers.

For operations using aggressive media, a BC nozzle is not just a spare part—it is a productivity investment. The venturi shape further enhances performance by maximizing particle exit velocity, which is essential for achieving the required surface profile on steel structures, castings, and fabricated components.

Venturi Nozzle Performance and Selection

The 5.5 mm (approx. 7/32 inch) bore is a common mid-range size, suitable for a wide variety of blasting applications. It provides a good balance between abrasive consumption, air demand (CFM), and cleaning rate. The venturi design accelerates air and media through a converging-diverging internal profile, resulting in a supersonic exit velocity and a tight, powerful blast pattern.

Selecting the correct nozzle bore involves matching it to your compressor's output and the job requirements. A 5.5 mm orifice typically pairs well with a No. 5 or No. 6 blast nozzle holder and is used in both manual and automated blasting cabinets or field blasting pots. Always verify the thread size and holder compatibility before ordering.
