Overview
Tin plating is used extensively on many ferrous and nonferrous metals. Tin is a gray-white, soft, and ductile metal that is not easily oxidized in air. Electrodeposited tin has good conductivity and corrosion resistance while enhancing the solderability of substrates that are not otherwise easily soldered. Tin is generally considered nontoxic and non-carcinogenic, so it is generally approved for food-contact applications. It is also widely used in bus bar and aerospace applications.
Applications and Specifications of Tin
Tin plating is provided in two general types of deposits: bright tin and matte tin. Both can be obtained from an alkaline or acidic bath and can be electrolytically applied. The acidic chemistries are most common today.
