Process description
Copper is a metal of a reddish colour, it crystallises in a regular pattern.
The process of copper-plating is used for protective and decorative purposes to extract copper as one of numerous layers (copper -nickel -chromium) as well as for technical purposes.
Application of a copper layer in the system of decorative and protective layers (Cu-Ni-Cr) allows for:
- reduction of costs of galvanisation (lower price of copper than that of nickel)
- improvement of resistance to corrosion thanks to efficient closing of surface pores
- improvement of appearance of products (perfect micro smoothing)
The most important product features:
- for protective and decorative purposes
- for technical purposes
- reduction of costs of galvanisation
- improvement of resistance to corrosion
Types of copper-plating baths:
- Cyanide-alkaline baths
Advantages:- They facilitate producing coatings on such materials as: steel, zinc alloys, aluminium alloys, magnesium alloys, with a guarantee of good adhesion
- Great profundity and covering
- Easy exploitation
- Acid baths
Advantages:- perfect ability of micro smoothness
- perfect shine
- good profundity and covering

Copper-plating is carried out in the fully automatic barrel line put in to service in November 2007
Purposes of copper layers:
- automotive industry
- electronics
- electrotechnics
- telecommunications
- sanitary fittings
- furniture industry
