ZIPPER COMPONENT AND SLIDE ZIPPER, AND METHOD FOR PRODUCING ZIPPER COMPONENT

摘要

A zipper component (1) comprising a component body (2) made of a metal and a metal plating film (3) provided on the surface of said component body. In this zipper component (1), at least a part of said component body (2) has been thermally treated before bending and thus said metal plating film (3) has a recrystallized structure wherein at least a part thereof has been recrystallized. Since the ductility of the metal plating film (3) can be improved thereby, when the zipper component (1) is bent, the metal plating film (3) can be deformed to follow the deformation of the component body (2). Therefore, the occurrence of crevicing or cracking in the metal plating film (3) can be prevented.
