Abstract: CuCr alloys are important contact materials, but all conventional preparing methods have disadvantages and mismatch the requirements for mass production and high-properties. The CuCr25 alloys were prepared by means of arcsmelting in vacuum, and their microstructures, physical properties as well as dielectric strength were investigated. The experimental results show that vacuum arc-smelting is an ideal method to produce CuCr25 contact alloys with fine microstructure, low gas content, high density and dielectric strength. Meanwhile, with the high productivity and low cost, CuCr25 contact materials can be produced with mass production through vacuum arc-smelting method.
