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
                 Superior rigidity
                 Capable of being fabricated to complex geometries
                 Concentricity held to within 0.01 mm      

Photos above demonstrate these merits.

Technical Data

       Hardness value:            1,400 – 1,600 HV or 1.7 times that of the hardened carbon steel
                                 
       Young's modulus:         450 - 650 MPa

       Fracture toughness:     6 - 8 MPa m^1/2

       Surface roughness:      0.05 – 0.1 microns or 2 – 4 micro inches Ra.

       Bore diameter:             Choice of  Ø 0.1, 0.14,  0.2,  0.3,  0.4,  0.5,  0.6,  0.7,  0.8,  1.0,
                                                                       1.1, 1.2, 1.3, 1.4, 1.5,  2.0 mm.

       Outside diameter:         Ø 0.5 – 6.0 mm, wall thickness governing.

       Length:                           10 – 100 mm, aspect ratio governing.

The Wire Guide Nozzles Part Numbering System innovated by COSMOS in 1993 is applicable in describing our 1-diameter and 2-diameter wire guide nozzles.  The 3-diameter and complex geometry wire guide nozzles are best described in dimensional drawings.
