The Merits of Solid Tungsten Carbide Nozzles

          Our wire guide nozzles in Solid Tungsten Carbide offer the following advantages:

                 Thoroughly mirror finished wire entrance, exit and bore surfaces
                    eliminate insulation damage
                 Superior rigidity
                 Capable of being fabricated to complex geometries
                 Concentricity to within 0.01 mm      

            Images above validate the merits.

Technical Data

       Hardness value: 1,400 – 1,600 Vickers, which is 1.7 times that of hardened carbon steel
                                    (See Hardness Comparison - Wikipedia for hardness conversion )
