A composite material including a composite film formed on a base material, the composite film including a silver layer containing carbon particles, wherein a content of Sb in the composite film is 1 mass % or less, and a crystallite size of silver in the composite film is 40 nm or less.

Composite material, method for producing composite material, and terminal

There is provided a composite plating material and a related technique thereof, the composite plating material including: a base material, and a composite plating layer on the base material, the composite plating layer comprising a composite material containing carbon particles and Sb in an Ag layer, with a carbon content of 6.0 mass % or more and a Sb content of 0.5 mass % or more.

Composite plating material and method for producing the same

There are provided a composite plated product wherein a composite plating film of a composite material containing carbon particles in a silver layer is formed on a base material and wherein the amount of the carbon particles dropped out of the composite plating film is small, and a method for producing the same. After a composite plating film of a composite material containing carbon particles in a silver layer is formed on a base material (of preferably copper or a copper alloy) by electroplating using a silver-plating solution to which the carbon particles are added, a treatment for removing part of the carbon particles on the surface thereof is carried out.

Composite plated product and method for producing same

There are provided a tin-plated product which has a zinc plating layer on the surface thereof and which has good corrosion resistance and good adhesion of the zinc plating even if the connecting portion of a terminal of the tin-plated product to an electric wire of aluminum or an aluminum alloy is not processed during press fitting such as swaging (or caulking) when the tin-plated product is used as the material of the terminal which is to be connected to the electric wire by press fitting, and a method for producing the same.
