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.

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.
