Abstract
Based on the resistance theory of metals, the influence of phase structure on the electrical conductivity of CuCr alloys is analyzed. The electrical conductivity is calculated under different phase structure models. By comparison with measurements, the utility of these models are discussed. Some influencing factors on the conductivity of CuCr are summarized. Several ways to improve the electric conductivity of CuCr alloys for vacuum switch applications are presented
