Boron carbide nozzles offer the longest wear life of any standard nozzle material. Peak nozzle production performance is maintained for longer periods with optimum consumption of air and abrasive. Boron carbide nozzles typically outwear tungsten carbide nozzles by five to ten times and silicon carbide by two to three times. Boron carbide nozzles are recommended for use with abrasives such as aluminum oxide and aggressive mineral aggregates. Our selection of nozzles is unmatched, anywhere We have standard products that can replace the original nozzles installed on most equipment. We also have higher performance upgrades for most OEM products to allow you to achieve optimum blasting effectiveness, efficiency and reduce your total costs.
