COPPER TUNGSTEN - TELLURIUM COPPER - TUNGSTEN CARBIDE - TUNGSTEN WIRE  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.  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. click here to download copper tungsten rounds stock sizes Copper tungsten tubes are stocked in 7" and 8" lengths, with a +/-.001" tolerance up to .125" OD.  click here to download copper tungsten precision tube sizes Copper tungsten plates are stocked from 3/32" to 2" thick, in widths of 2" or 4".  click here to download copper tungsten plate stock sizes Copper tungsten squares are available from 1/8" to 2" square, 8" long from stock. click here to download copper tungsten square stock sizes Copper tungsten precision rods have a tolerance on the OD of +/-.0005".   Please note that some rods may only be available in 7" or 6" lengths, depending upon the availability of materials.  click here to download copper tungsten precision rod sizes up to .120" OD Copper tungsten strips are available from .005" to .079" thickness.  Some minimum order quantities may apply. click here to download copper tungsten strip stock sizes

Tellurium copper electrode material contains approximately 1-1/2% tellurium, which improves the machinability and fabrication process of electrodes for EDM compared to brass, 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. Download our catalogue of stocked sizes of tellurium copper.
