TETRABOR SAND-BLASTING NOZZLES
The boron carbide is, after diamond and cubic boron nitride (CBN), the hardest material available on market.
The extreme hardness of TETRABOR nozzles assures the greatest resistance to wear, even with particularly hard abrasives like corundum and silicon carbide. TETRABOR nozzles are made of pure boron carbide (B4C) with no binders and consequently result extremely light (boron carbide = 2,51 g/cm3 - tungsten carbide = 15g/cm3 approx.).
This material allows to maintain unaltered the optimal nozzle hole diameter as long as possible, even under extreme stress.
TUNGSTEN-CARBIDES NOZZLES
Sintered tungsten-carbides nozzles highly resistant to wear, provided with an external steel shock-proof housing. For large walls it is recommended the use of a "Venturi tube" nozzle provided with sections which assure the highest outcoming speed and the lowest operating costs.
