| Abstract: | The voltage withstanding capability and electric conductivity of CuCr contact materials with low chromium content and fine Cr particles were studied. The results show that the withstanding voltage has little relation with the Cr content for the melted casting CuCr alloy within 15%29% Cr content, and that the electric conductivity of the alloy increases with the decreasing of Cr content. |
