Effect of Tungsten Powder Granularity on W-Cu Electrode II

Tungsten powder granularity has an effect on the density, the hardness and the electrical conductivity of tungsten copper electrode.

2. Effects on the Density and Hardness of Tungsten Copper Electrode

The experiment result shows that with the increasing powder granularity, the density of W70-Cu alloy is a trend of decreasing after infiltration. For instance, when tungsten powder granularity of W-30Cu is 2.65μm, the hardness is up to HB222. But the larger powder granularity, the lower hardness, and the lowest hardness is HB190 with 2.65 power granularity. The principle is that although tungsten has high density (19.3g/cm³), it belongs to fragile material. The finer power, the more active sintering, the more obviously shrinking of volume, which increases the content of W and improve the density and hardness of tungsten copper electrode.
