Decorative and protective surfaces – copper
High-gloss, ductile layers with fine crystals are precipitated in an electrolytical process. Both acidic and cyanidic electrolytes are used. Copper has good covering properties and is mostly used as a substructure for other galvanic surfaces such as nickel and chrome. Cu/Ni and Cu/Ni/Cr coating systems fulfil numerous requirements in terms of corrosion protection, while providing a decorative appearance. Copper is often also used as an independent, functional or decorative plating. In addition to standard substrates such as iron and Cu-Zn materials, zinc die cast parts, powdered metals and aluminium are also plated.
