We employ powder metallurgy to manufacture high-voltage tungsten-copper contacts: 
out of the mixture of W and Cu (high copper content) by the infiltration of a tungsten matrix with copper (low copper content)

The starting powders have a high purity (W ≥ 99.9%), fine electrolytic Cu powderes. Because of its properties (Table 2) W-Cu is used for:

electrical contact materials

welding and erosion electrodes
