What is Tin Plating?
Tin plating is an electrolytic process that deposits a layer of tin onto the surface of ferrous or non-ferrous materials to enhance corrosion resistance and surface conductivity. Widely used across various industries, tin is a non-toxic, ductile metal that offers excellent corrosion protection, making it especially valuable in food processing and electronics. It also provides sacrificial protection for metals like copper and nickel, although it does not offer this benefit for steel substrates. At Advanced Metal Finishing, we’re proud to provide one of the brightest and most uniform tin finishes available on the market.
Why Use Lead-Free Tin?
Lead-free bright tin is a soft metal known for its high electrical conductivity and reliable corrosion resistance. This type of finish is commonly used to maintain the solderability of underlying layers such as copper or nickel. In connector applications, we recommend using at least 100 grams of contact force to ensure proper engagement. For optimal performance, a sliding or wiping contact method is advised during mating. Our lead-free tin plating complies with RoHS standards and is designed to meet modern performance and environmental requirements.
