Processes

Tin plating

Tin is characterised by significant electrical potential. It is extremely conductive, solderable, self-lubricating and compatible with foods. The tin surface also has multiple functional properties, such as corrosion protection, chemical resistance, high ductility and good layer thickness distribution. Its silver-white appearance makes tin a popular alternative to silver.

With all of its functional and decorative properties, tin layers can be used in almost all industrial sectors. Especially in electronics and electrical engineering, automotive and food industries, and in mechanical engineering. In combination with other layers, the functional properties of tin layers can be further modified.

Tin surfaces in the portfolio


Galvanic tin process

In tin plating, a silver-white surface is produced in an electrolytic tin bath, which is covered with a thin layer of oxide in air. The base material is primarily steel, non-ferrous metals and aluminium with an intermediate layer. In addition to its decorative appearance, the tin surface has multiple functional properties, such as corrosion protection, chemical resistance, high ductility and good layer thickness distribution.

Lead-free tin

Our tin process is lead-free and therefore complies with Directive 2002/95/EC(RoHS) of the Electrotechnical and Electronic Industry, as well as the End-of Life Vehicles Directive.

Combination coatings

In combination with other layers - SkinTech® - the functional properties of tin layers can be further modified.
