Nickel plating is ideal for pieces where you want to add a little shine and protect the base material from corrosion.
Nickel is also used as such in many applications.
The nickel surface is hard, pleasant to look at and provides reasonable protection to the base material.
Nickel plating can be carried out in different types of baths and the nickel coatings obtained vary widely in their properties.

Nickel plating & standards:
- Electroplated coatings of nickel for engineering purposes (ISO 4526:2004)
- Electrodeposited coatings of nickel plus chromium and of copper plus nickel plus chromium (1456:2009)
- Electrodeposited coatings of nickel (ISO 1458:2002)
Semi-bright nickel plating provides better corrosion protection than bright nickel plating.
Semi-bright nickel plating has low internal stresses and therefore good ductility and elongation.
The structure of the nickel plating coating is lamellar.
Additives are used to achieve the best possible smoothness and sharp gloss, in order to reduce or eliminate the need for mechanical grinding and polishing of the part.
Corrosion resistance is not as good as that of semi-finished nickel.
Double layer nickel plat ing refers to a plating process in which nickel is first precipitated from a semi-bright bath and then a full bright bath is deposited on top.
The sulphur-rich layer is less noble than the sulphur-free lower layer, and provides cathodic protection.
The combination gives very good corrosion protection.
The satin nickel plating gives a pleasing and decorative finish, suitable for a wide range of applications.
The coating is formed by the incorporation of small solid particles into the coating by the precipitation of nickel.
Black nickel plating gives a beautiful black finish.
It is most commonly precipitated over semi-gloss or polished nickel.
