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.
Copper
- Clear levelling effects, good pre-treatment for ZN die-cast or sintered moulded components.
- Very good heat conductivity
- Excellent electrical conductivity
Copper surfaces have a decorative, reddish surface, which can be subsequently dyed if necessary. Once it has been given an antique finish, this creates an attractive and wear-resistant top coat.
- Automotive (frequently used are Cu/Ni or Cu/Ni/Cr coating systems)
- Consumer industry (household implements, as substructures or coating systems)
- Electrical industry
- Mechanical engineering
