Abstract: The effects of drawing deformation and electic magnetic stirring (EMS) on microstructure, Cu dendrite orientation, tensile strength and electrical conductivity of Cu-6%Ag alloy were studied. The results show that diameter and spacing of the fibroid second phase in the alloys with and without EMS decreased with the increase of drawing deformation, and their tensile strength increased and their electrical conductivity was less than the casted alloy′s. The casted alloy with EMS had no Cu dendrite orientation, and drawing made 〈111〉 direction increasing. The diameter and spacing of the fibroid second phase in the alloy with EMS was larger than that in the alloy without EMS, but its combination properties of tensile strength and electrical conductivity were better. EMS had little effects on tensile strength of drawn alloy wire, but could made its electrical conductivity increasing.
