Tungsten Carbide Aluminium Jacket Nozzle Tungsten carbide nozzles have long been the traditional material selection for most general nozzle applications and where medium cutting abrasives like glass bead, steel shot & grits, or Copper slag are used. These widely used, robust nozzles are the preferred choice of blast cleaning operators, as it has excellent durability & wear when using the hard abrasive. Nozzle Size NTL-450 1/4” Tungsten carbide Venturi No4 NO.5 NOZZLE BORE 1/4" / 8.0mm LENGTH- 5 1/4" /136mm AIR REQUIREMENT 150/170 CFM NTL-550 5/16” Tung- sten carbide Venturi No5 NO.5 NOZZLE BORE 5/16" / 8.0mm LENGTH- 5 3/4" /147mm AIR REQUIREMENT 150/170 CFM NTL-650 3/8” Tungsten carbide Venturi No6 NO.6 NOZZLE BORE 3/8" / 9.5mm LENGTH- 7" /180mm AIR REQUIREMENT 250/265 CFM NTL-850 1/2” Tungsten Carbide Venturi No8 NO.8 NOZZLE BORE ½” / 12.5mm LENGTH- 9 1/4" /235mm AIR REQUIREMENT 350/425 CFM Silicon Composite Nozzle Silicon nozzles are probably the most popular alternative to tungsten carbide for blast nozzle applications. The low wear rate maintains the internal nozzle geometry and provides maximum blasting effectiveness, minimum compressor requirements and reduced downtime due to replacement. Silicon is also about one fifth lighter than Tungsten Carbide, so it is an excellent choice to minimize operator fatigue and maximize productivity.
