TETRABOR® Blast Nozzles

ESK TETRABOR® Boron Carbide blast nozzles pay off thanks to their extreme abrasion resistance. Boron Carbide (B4C) is one of the hardest engineering materials available. TETRABOR® blasting nozzles guarantee minimum wear and have an exceptionally long service life even in applications requiring extremely hard abrasives such as corundum and Silicon Carbide. Boron Carbide is the choice of material for heavy-duty tools and blasting techniques. With a density of more than 2.50 g/cm3 offers TETRABOR® Boron Carbide clear advantages:

-Outstanding cost benefits thanks to its extreme wear resistance
-Low air consumption through minimal widening of the bore
-Constant operating conditions and uniform blasting performance
-Unrivalled service life with all blasting agents

EKasic® Blast Nozzles

ESK blast nozzles of EKasic® Silicon Carbide also offers a range of advantages:
-Outstanding cost efficiency
-Infrequent maintenance
-Constant operating conditions and uniform blasting performance
