Copper and copper coating systems

Decorative and protective surfaces - copper

Brief technical description:

• 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 coating. In addition to standard substrates such as iron and Cu-Zn materials, zinc die cast parts, sintered components and aluminium are also coated.

Advantages:

• Clear levelling effects, good pre-treatment for ZN die-cast or
• sintered moulded components.
• Very good heat conductivity
• Excellent electrical conductivity

Please note:

• 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.

Area of utilisation:

• 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
