A copper alloy wire and a method of manufacturing

A copper alloy wire of the present invention, a copper matrix phase, and a composite phase of short fiber containing a dispersed copper mother phase Cu The copper alloy wire has a melting step of obtaining a melt by dissolving the raw material such that the copper alloy containing Zr in the range of less than 0.2 at% or more 1.0 at%, the casting process of obtaining an ingot by casting the molten metal If, ingot comprises a drawing step of drawing in cold treatment after drawing process and drawing process can be obtained by carrying out at less than 500 ° C..
