Advantage:Longer service life. In terms of service life, boron carbide nozzle has the longest one such as for sandblasting and shot peening.
Lower cost per use. Boron carbide costs more but will outlast tungsten carbide by 3-10 times.

Our Abrasive Blast Nozzles (include 1 1/4” fine and 2” coarse threaded standard venturis and other non-standards parts) which are mostly made from Boron Carbide (B4C), Silicon Carbide (SiC) and Tungsten Carbide (TC) are widely used in surface preparation and industrial cleaning such as shipyard-cleaning and indoor and outdoor blasting, finishing and deburring.
Here is the life-time contrast list (Hours) of Boron Carbide (B4C), Silicon Carbide (SiC) and Tungsten Carbide (TC) nozzles against general abrasives:
