COPPER TUNGSTEN

  • Copper tungsten is used as an electrode material to EDM carbide or other exotic materials.  Copper tungsten has excellent wear properties but is more challenging to machine to shape.
  • Copper Tungsten is sold in bars, thin sheets, rounds and squares.  Our stock items of copper tungsten are the 70/30 - 70% tungsten and 30% copper - the most common grade used in EDM applications.  We also supply 60/40 and 75/25 grades for specific applications and many sizes of ELKONITE® copper tungsten.
  • Files with our stock sizes of copper tungsten are listed below.  Other sizes are available upon request.
    • Copper tungsten rounds are 8" long, but are also available up to 12" long.
    • Copper tungsten tubes are stocked in 7" and 8" lengths, with a +/-.001" tolerance up to .125" OD.
    • Copper tungsten plates are stocked from 3/32" to 2" thick, in widths of 2" or 4".
    • Copper tungsten squares are available from 1/8" to 2" square, 8" long from stock.
    • Copper tungsten precision rods have a tolerance on the OD of +/-.0005" up to a diameter of .120”.   Please note that some rods may only be available in 7" or 6" lengths, depending upon the availability of materials.
    • Copper tungsten strips are available from .005" to .079" thickness.  Some minimum order quantities may apply.

TELLURIUM COPPER

  • Tellurium copper electrode material contains approximately 1-1/2% tellurium, which improves the machinability and fabrication process of electrodes for EDM compared to standard copper, without affecting the EDM characteristics. The photograph shows regular copper on top, with the characteristic burr - and tellurium copper on the bottom as a contrast.
