WCu80 Ring / Rod / Sheet / Bar Tungsten Copper EDM Electrode
Description:
tungsten composites 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.
