Galvanic copper
copper coatings - base for further electroplated coatings
Copper serves as a base for further electroplated coatings, such as tin or nickel. The procedure starts with the deposition of sparkling, microcrystalline and ductile copper coatings in an electrolytic process. The advantage of a finished copper-nickel coating system: It fulfills numerous requirements when it comes to corrosion protection accompanied by attractive looks. Copper is characterized by good covering properties, high ductility and excellent electrical and thermal conductivity. When applied as a base coating, it counteracts strains between the component and the coating system. What is more, copper coatings are also suitable for subsequent passivation.
Fields of use
In the technical field, copper is used in electroplating as an intermediate layer before silver plating or nickel plating of copper and copper alloys. The coating is cyanidal or acidic electrolytes depending on the material.
The reddish color when coppering is interesting for the decorative area. A copper coating can be easily polished, has a good ductility, but copper is not start-up resistant.
