摘要： After drying the surface of a tin plating layer having a thickness of 0.4 to 3 μm which is formed on a base material of copper or a copper alloy by electroplating at a current density of 5 to 13 A/dm2 in a tin plating solution consisting of water, tin sulfate, sulfuric acid and a surfactant, the surface of the tin plating layer is heated to melt tin, and then, cooled to cause a layer of the tin plating layer on the side of the outermost surface to be a tin layer, which has a structure obtained by solidification after melting, while causing a layer of the tin plating layer between the tin layer and the base material to be a copper-tin alloy layer, to produce a tin-plated product wherein a tin layer, which has a structure obtained by solidification after melting, is formed on a copper-tin alloy layer formed on a base material of copper or a copper alloy and wherein the tin-plated product has a glossiness of 0.3 to 0.7.

摘要： There is provided a tin-plated product having an excellent minute sliding abrasion resistance property when it is used as the material of insertable and extractable connecting terminals, and a method for producing the same. After a nickel layer 16 is formed on a substrate 10 of copper or a copper alloy so as to have a thickness of 0.1 to 1.5 μm by electroplating, a tin-copper plating layer 12 containing tin 12b mixed with a copper-tin alloy 12a is formed thereon so as to have a thickness of 0.6 to 10 μm by electroplating using a tin-copper plating bath which contains 5 to 35% by weight of copper with respect to the total amount of tin and copper, and then, a tin layer 14 is formed thereon so as to have a thickness of 1 μm or less by electroplating if necessary.
