Tin

Why is tin such a popular choice for electroplating? Perhaps the biggest reason is that tin plating — or “tinning” — is an extremely cost-effective process. Because tin is so readily available, it is much less expensive than pricier metals such as gold, platinum or palladium. Tin also offers excellent solderability as well as superior protection against corrosion.

Tin plating can produce a whitish-gray color that is preferable when a dull or matte appearance is desired. It can also produce a shiny, metallic look when a bit more luster is preferred. Tin offers a decent level of conductivity, making tin plating useful in the manufacturing of various electronic components. Tin is also FDA approved for use in the food service industry.
