Tungsten Copper For EDM and ECM
Tungsten copper alloy (WCu) are used worldwide for EDM (Electrical Discharge Machining) and ECM (Electrochemical Machining) electrodes. All material is manufactured by the press, sinter, and infiltrate process. Virgin powders are used, resulting in a consistent homogeneous material giving high and even burning rates. Copper tungsten is used in plunger/sinker applications where intricate definition is required, especially in tungsten carbide.
Tungsten copper for EDM and ECM applications are far superior when fine surface finishes, deep narrow slots or ribs and small precise holes are required. Tungsten alloys are preferred when matching extremely detailed sections. In the ECM process, Copper-Tungsten withstands erosive effects of short circuit malfunctions far better than other materials.
