Provided is a metallic fastener member which has a specific color, i.e., a light gold color, and has all of practical strength, unsusceptibility to discoloration, and processability. The metallic fastener member comprises, as the base material, a copper alloy having a composition which contains 1-30 mass % Zn and 1-11 mass % Ni, with the remainder comprising Cu and unavoidable impurities, and has a Vickers hardness of 120 Hv or greater but less than 220 Hv.

The present device provides a slide assembly for a zipper, and a method for manufacturing a zipper slide assembly. The slider assembly is formed in a single die cast operation to include the slider and the pull member being formed simultaneously. Whereby the bridge and pull loop are formed with their full geometric shape and without converging flat surfaces caused by tooling limitations found in the prior art.

A method of manufacturing a cap structure includes providing an initial cap body; placing an elastic piece on an inner surface of the initial cap body; and then punching the initial cap body to form a cap body. The cap structure includes a cap body and an elastic piece. The cap body has at least two first inner concave grooves, at least two first retaining blocks and at least two first through holes. The at least two first inner concave grooves are disposed on the inner surface of the cap body, and the at least two first through holes pass through the cap body. The elastic piece is disposed on the inner surface of the cap body, and the at least two first retaining blocks contact the elastic piece for retaining or abutting the elastic piece.
