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
50
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.
