Ni-doped Effects on Tungsten Copper Electrode

Except cobalt (Co) element, Nickel (Ni) is also a kind of common additives, and the density, the hardness, the electrical conductivity and other comprehensive properties of tungsten copper electrode will be influenced by the content of Ni. The effect of content of Ni on the density and hardness of tungsten copper W-25Cu electrode as follow:

The diagram shows that the density and the hardness of tungsten copper electrode is sensitive to the adding Ni element. When the content of Ni is 0.3%, the density rapidly increases 14.9g/cm³ to 17.0g/cm³. Therefore, adding Ni element will improve the density and the hardness of tungsten copper products.
