ABSTRACT:
An exemplary copper-silver alloy wire includes a conductive core containing copper, and a copper-silver cladding layer surrounding the conductive core. A ratio of silver to copper by weight in the copper-silver cladding layer is in a range from 1% to 30%. An exemplary method for manufacturing the copper-silver alloy wire includes steps of: providing a conductive core containing copper; forming a silver layer surrounding the conductive core; and heating the silver layer and peripheral portions of the conductive core so as to form a copper-silver cladding layer at an interface between the silver layer and the conductive core. The copper-silver alloy wire has high electrical conductivity, low current loss and high anti-interference.
