摘要:
A metallic material for a connecting part, having a rectangular wire material of copper or a copper alloy as a base material, and formed at an outermost surface thereof, a copper-tin alloy layer substantially composed of copper and tin, wherein the copper-tin alloy layer of the outermost surface further contains at least one selected from the group consisting of zinc, indium, antimony, gallium, lead, bismuth, cadmium, magnesium, silver, gold, and aluminum, in a total amount of 0.01% or more and 1% or less in terms of mass ratio with respect to the content of the tin.
摘要:
A terminal for a connector, fabricated from a metallic material for a connector which material has a tin layer or a tin alloy layer formed on a base material of copper or a copper alloy, wherein the thickness of the tin layer or the tin alloy layer at a contact, site on the surface of the terminal is smaller than the thickness of the tin layer or the tin alloy layer in the areas other than the contact site, and a copper-tin alloy layer is formed as an under layer of the tin layer or the tin alloy layer at the contact site; and a terminal for a connector, fabricated from a metallic material for a connector which material has a base material of copper or a copper alloy, wherein a copper-tin alloy layer is formed in a spot shape at a contact site on the surface of the terminal, and a tin layer or a tin alloy layer is formed in the remaining areas on the surface of the metallic material.
摘要:
A connector including a male terminal and a female terminal, at least the contact point part of at least one of the terminals having an outermost layer made of a metallic material which is a Cu-Sn alloy layer in which the copper concentration gradually decreases toward the surface. Also provided is a metallic material which is for use in this connector and includes an outermost layer constituted of a Cu-Sn alloy layer in which the copper concentration gradually decreases toward the surface.
