    Abstract:

    W-Cu alloy has been applied in metallurgy, materials, electronics, military and other fields because it has good arc-resistance, anti-welding, conduct heatSandSelectricity and so on. Electrical conductivity is one of the important material performanceSindexes and has attractedSmuch attention. The electrical conductivity models of W-Cu alloy with different content of Cu are studied in this paper. The characteristics and applicableSrangesSofStheseSmodels is also discussed. The conductivity are calculated by using these models and compared with the experimental results and the theoretical values. The suitable theoretical values of W-Cu alloy are selected and compared to the experimental values. The results show the experimental conductivity is basically consistent with the theoretical values for W-Cu alloy with low or high Cu component. Enhancing copper content and reducing porosity lead to increasing the conductivity of W-Cu alloy. This offers the theoretical basis to design the constituent and electrical conductivity of W-Cu alloy.
