bore size 4.8mm 6.4mm 7.9mm silicoon carbide boron carbide sandblasting nozzle insert
Boron carbide (B4C) is one of the world's hardest manufactured materials. Its strong chemical bonds and hard surface minimize wear in rigorous environments.
Advantages of our boron carbide nozzle/B4C nozzle:
Low density
Exceptional hardness
Neutron absorbing
How to choose material for the nozzles?
Tungsten Carbide, Boron Carbide, and Silicon Carbide are the three most popular materials used today for blast nozzles. Boron Carbide nozzles are the hardest of the three, followed by Silicon Carbide, and then by Tungsten Carbide. Hardness is necessary to order to withstand the wear and tear that the blast nozzle liner will be exposed to by the abrasive used.
You can use a boron carbide blast nozzle anytime you are using aluminum oxide or silicon carbide as your abrasive blasting media.
Estimated Service Life of Nozzles (In hours)
Nozzle Material | Steel Grit/Shot | Silica Sand | Brown Aluminium Oxide |
Alumina | 20-40 | 10-30 | 1-4 |
Tungsten Carbide | 500-800 | 300-400 | 20-40 |
Silicon Carbide | 600-1000 | 400-600 | 50-100 |
Boron Carbide | 2000-2500 | 1000-1500 | 500-1000 |
Boron carbide nozzle has the longest use life compared with tungsten carbide nozzles, silicon carnode nozzles and Aluminia nozzles.
