Patent abstract
There is provided a tin-plated product which has a small deterioration of contact resistance with age, an excellent wear resistance and a low coefficient of friction. A coating of a composite material, which contains 0.1 to 1.0 wt % of carbon particles dispersed in a tin layer and which has a thickness of 0.5 to 10.0 μm, preferably 1.0 to 5.0 μm, is formed as the outermost layer of a substrate. Thus, the coefficient of dynamic friction between the tin-plated products of the same kind is 0.20 or less, and the coefficient of dynamic friction between the tin-plated product and a reflow tin-plated product is 0.20 or less, while the contact resistance is 1 mΩ or less.
