The effects of additive Ni and Co on the microstructures and characteristics of CuCr25 alloys prepared by vacuum induction melting have been studied. The results show that both Ni and Co eliminate Cr segregation, and significantly improve the microstructures of CuCr25 alloys. The additive Ni and Co also increase the dielectric strength of the alloys, but slightly decrease electrical conductivity. As a result, the properties of vacuum induction melted CuCr25 alloys reach the specifications of conventional CuCr50 alloy.
