Blast Nozzles
| Nozzle material selection depends on the abrasive you choose, how often you blast, the size of the job, and the rigors of the job site. Here are general application guidelines for various materials.
Aluminum Oxide "Alumina" Nozzles offer good service life at a lower price than other materials discussed here. They are a good choice in low usage applications where price is a primary factor and nozzle life is less important.
Tungsten Carbide Nozzles offer long life and economy when rough handling can't be avoided and mineral and coal slag abrasives are used. All tungsten carbide nozzles are not equal. Note that all Boride tungsten carbide nozzles feature top wear grade material and thick-wall construction.
Silicon Carbide Composite Nozzles offer service life and durability very near tungsten carbide, but these nozzles are only about one-third the weight of tungsten carbide nozzles. Silicon carbide composite nozzles are an excellent choice when operators are on the job for long periods and prefer a lightweight nozzle.
Boron Carbide Nozzles provide longest life with optimum air and abrasive use. Boron carbide is ideal for aggressive abrasives such as aluminum oxide and selected mineral aggregates when rough handling can be avoided. Boron carbide will typically outwear tungsten carbide by five to ten times and silicon carbide by two to three times when aggressive abrasives are used.
Service Life Comparisons. (Approximate Service Life in Hours)
Nozzle Material:.................Steel Shot/Grit....................Sand..............Aluminum Oxide
Aluminum Oxide.......................20-40............................10-30....................1-4
Tungsten Carbide...................500-800........................300-400................20-40
Silicon Carbide.......................500-800........................300-400................50-100
Boron Carbide......................1500-2500......................750-1500............200-1000
These are estimated values for comparison only. Actual service life will vary depending on blast pressure, media size, and particle shape.
