Hot sale Tungsten Copper alloy EDM electrode W80Cu20
WCu alloys 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.
Resistance welding electrode
A combination of the advantages of tungsten and copper, high temperature resistance, electric arc ablation, high intensity, than the major,
Advantages
High thermal conductivity
Excellent hermeticity
