Tinning
Tinning is a galvanic process, highly appreciated in the electronic and electromechanical sectors, mainly used to improve corrosion resistance and solderability. It is also widely used in the food and hydrosanitary sectors for its compatibility with water used for human consumption.
Supergalvanica specializes in aluminum treatment and holds certification of suitability according to D.M. 06-04-04 for coating materials intended for contact with drinking water.
Technical Characteristics
Consists of an alkaline bath for both matte and glossy finishes, executable with variable thickness on request from 1 to 30 microns. Generally, before tinning a brass item, a copper underlayer is deposited to prevent zinc migration from the brass alloy to the tin layer. In the case of aluminum products, the underlayer can be copper or nickel depending on the requirements. The final color of the product is silver-white.
