Tungsten copper electrode for EDM and ECM:

      Our tungsten copper electrode for EDM and ECM is manufactured by the press, sinter, and infiltrate process. In order to reach a consistent homogeneous material giving high and even burning rates, we use virgin and excellent powders. Tungsten copper alloys are used worldwide for EDM (Electrical Discharge Machining) and ECM  (Electrochemical Machining) as electrodes. Tungsten copper is used in plunger/sinker applications where intricate definition is required

Advantages:

High thermal conductivity

Low thermal expansion

High wear resistance combined

Excellent electrical conductivity

  Chemical Composition:

Application:

Copper tungsten electrodes and tungsten silver electrodes are widely used for machining tungsten carbide, PCD tools and high speed steel.  The electrical conductivity increases with the amount of copper and the electrode wear increases with the amount of tungsten.  The majority of copper tungsten electrodes for EDM are 70% tungsten, 30% copper mixture. (Except rolled sheet which is 60% tungsten, 40% copper.) Other mixtures are available such as 80% tungsten, 20% copper; 75% tungsten, 25% copper, etc.  

Zhuzhou Newmetal Materials Co., Ltd is a refractory metal manufacturer specializing in the raw material and deep-processing product of tungsten, molybdenum, tantalum, niobium, rhenium and tungsten carbide.

• We have conquered the technological difficulties in welding between the tungsten carbide wear-resistant material and stainless steel-based and iron-based. The geometrical tolerance of weldment can be controlled in level A.

• Relying on powder metallurgy institute and engineering materials institute of Central South University, We have established a production-learning-research base to provide powerful technologic support for products R&D. And we have the whole production equipment from mixing to finish machining, including the world’s most advanced cold isostatic pressing machine which can manufacture the widest and longest plate.

•Our 21 technicians, 10 after-sales personnel and 120 manufacturing workers are all heartedly at your service.
