Copper layers possess good adhesion properties and are ductile (easily deformable). Copper plating often serves as a carrier or intermediate layer for top layers such as nickel, tin, tin-lead alloy and silver on ferrous and non-ferrous materials. Copper is mainly used as the final layer in relay parts for corrosion protection of magnetic iron base materials.
