Tin Plating & Coating Services - Electris Coating Systems

The tin plating we perform at our electroplating shop is a process that is widely used in various industries. At Electris Coating Systems, we specialize in tinning copper components, as well as various aluminum alloys (copper tinning, aluminum tinning). Our specialty is the tinning of busbars.

The tin layer not only reduces the coefficient of friction but plays an important role in corrosion protection. That's why tin plating for metal components 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 and other non-ferrus metal parts. 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 metal components up to a maximum length of 2100 mm.

What does the non-ferrous metal tinning process consist of?

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 metal surface preparation. The metal to be treated must be perfectly degreased and thoroughly cleaned.

Advantages of the tin coating process in Electris factory

Tin coatings are widely used in the electrical and power industries due to their 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 bus bars and connectors. Often these galvanic coatings are used to coat copper parts, improving their solderability.

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

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.

Tinning copper ensures durable electrical conductivity while protecting the surface from oxidation. Although copper has very good conductivity, its surface easily forms a layer of oxides, which can lead to increased contact resistance. The tin coating acts as a protective barrier against atmospheric corrosion, ensuring that electrical connections maintain stable contact parameters and do not degrade during operation.

Tin Plating Methods

Tin plating can be performed using several methods, depending on the base material, desired coating thickness, and technical requirements of the component. The most common process is electrolytic acid tin plating, which provides bright, uniform coatings with good corrosion resistance. For components that require strong adhesion or are difficult to plate directly, alkaline tin plating (including cyanide-free baths) is used, ensuring excellent bonding strength. In addition, matte tin plating is applied where solderability is more important than decorative shine, while bright tin plating is preferred in electronics and consumer goods due to its attractive appearance. Each method ensures reliable performance when properly selected and controlled.
