Abstract (en)

The object of the present invention is to provide a copper alloy for slide fasteners which has excellent whiteness, does not contain nickel and hence does not have the problem of nickel allergy, and has excellent continuous castability and casting quality. The composition of the alloy for slide fasteners is represented by the general formula CuaZnbMnc, wherein regarding a, b and c, in mass%, 10 ≤ b ≤ 20, 8 ≤ c ≤ 15, and a is a remainder, with unavoidable impurities being contained. Moreover, the structure of the alloy is preferably made to be a single alpha phase at room temperature, and the surface of the alloy is plated.
