Good quality Wolfram Copper alloy EDM electrode W90Cu10
copper and its alloys constitute one of the major groups of commercial metals. They are widely used because of their excellent electrical and thermal conductivity, outstanding resistance to corrosion, and ease of fabrication, together with good strength and fatigue resistance. They are generally nonmagnetic.

Advantages
Higer thermal conductivity
Low thermal expansion
High arc resistance combined with good electrical conductivity
Applications
Tungsten copper 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 tungsten powders are used, resulting in a consistent homogeneous material giving high and even burning rates. Tungsten copper is used in plunger/sinker applications where intricate definition is required, especially in tungsten carbide.
