摘要： A wire material having a copper-zinc alloy layer, which is formed by action of thermal diffusion, and a zinc layer on its circumference surface is subjected to processes, including from a step of drawing the wire material to a step of reducing the diameter of the product, to reliably crash the copper-zinc alloy layer into particles. The particles are embedded in the circumference surface of a core to integrate the diffusion alloy layer and zinc layer with the core and prevent the diffusion alloy layer and zinc layer from falling off from the core. In addition, in order to cover cracks formed in the copper-zinc alloy layer during wire drawing with a zinc thin film, wire drawing is performed at temperatures appropriate for maintaining good malleability and ductility of zinc.
