Copper tungsten materials,Copper Tungsten Electrical Contacts,WCu Electrode material

Tungsten copper alloy is an alloy of tungsten and copper. Commonly used copper content of the alloy is 10% to 50%. Preparation of alloy powder metallurgy method has good electrical and thermal conductivity, good high temperature strength and a certain plasticity. At very high temperatures, such as above 3000 ℃, the alloy of copper is liquefied and evaporated to absorb a lot of heat, reducing the surface temperature. So this kind of material is also referred to as metal sweat material.

WCu Electrode material

Early EDM electrode made of copper or graphite electrodes, inexpensive but impatience ablation. Advantages of tungsten copper electrode is high temperature, high temperature strength, resistance to arc erosion, thermal conductivity and good performance, fast heat dissipation. Applications focused on EDM electrodes, welding electrode and high voltage discharge electrodes. EDM electrode is characterized by many different specifications, but the total amount of more than small quantities. As EDM Electrode tungsten copper material should have as high a uniformity of density and organizations, in particular the elongated rod, tubular and shaped electrodes.
