Tin is a silver-white and very soft metal. It is usually extracted from the tin mineral cassiterite or tin ore. Tin is mainly deposited from sulphuric acid electrolytes in electroplating. The structure of the deposited layer can be changed by adding mostly organic substances. It is therefore possible to deposit glossy layers in addition to a matt tin layer.
Tin is a preferred surface in the electrical and automotive industries because of its excellent resistance to humid and normal air and its good electrical conductivity at low contact resistance. Tin is therefore included in the portfolio at Rieger Metallveredlung. We are able to rely on a frame machine as well as a barrel machine in the processing of
