Tin plating

The tin plating we perform at our electroplating shop is a process that is widely used in various industries.

The tin layer not only provides excellent conductivity and contact efficiency, it reduces the coefficient of friction and, in some cases, plays an important role in corrosion protection. That's why tin plating for both copper and aluminum has gained recognition in many specialized sectors, such as energy, electronics and automotive.

At Electris Coating Systems, we specialize in tin plating for aluminum components as well as various copper alloys. We apply tin coatings in a wide range of thicknesses: from 1 μm to 50 μm, based on the requirements provided to us by our customers. We can galvanise components up to a maximum length of 2100 mm.

What the tinning process is all about?

The tin plating process is based on the application of tin layers using acidic or alkaline solutions that are rich in tin ions. The complex process results in the formation of a suitable layer of metal on the surface.

A key role in the entire process is played by proper surface preparation. The metal to be treated must be perfectly degreased and thoroughly cleaned.

Advantages of the tin plating process

Tin coatings are widely used in the electrical and power industries due to their good conductive and contact properties. Tin has low electrical resistance and good adhesion to other metals. These characteristics make it an ideal material for the manufacture of electronic components such as solder wires, leads and connectors. Often these coatings are used to coat copper wires, improving their solderability.

The main advantages of the electroplating process for copper or aluminium components are:

  • Good conductivity of the coating: tinning is designed to improve or change the conductive properties.
  • Corrosion protection: significantly increases corrosion resistance, protecting components from the elements.
  • Solderability: tin facilitates the soldering process, increasing the efficiency of manufacturing electrical and electronic equipment.
  • Oxidation resistance: tin is much less susceptible to oxidation than copper itself. This means that tin plating helps maintain the original appearance of copper for a longer period of time, which is important in aesthetic and decorative applications.
