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.
