Abstract

CuCr25 alloy is prepared by smelting in vacuum for the efficient production of contacts and saving Cu

Cr materials. The experiment results show that the dimension of Cr phase in the alloy is 30

μm

the relative density is higher than 98%

and the gas content is lower than 500 x 10-6Pa. The dielectric strength of the alloy reaches the same level as that of alloys prepared by conventional methods.
