Friction tinning

Friction tinning is a process used in metal processing to protect and improve surfaces by applying tin. In this process, tin is applied in molten form to the metal surface to be protected. The term "friction tinning" is derived from the method of application, in which the liquid tin is transferred to the metal surface by rubbing.

This process is often used on objects made of copper or other metals to prevent corrosion and increase durability. The object to be tinned is usually cleaned thoroughly before the process to ensure optimum adhesion of the tin. After application, the tin solidifies as it cools and forms a thin, protective layer on the surface of the metal.

Friction tinning is used in various industries, including the manufacture of kitchen utensils, electronic components and other metal products where increased resistance to environmental influences is required.
