Overview
Tin plating is used in applications to protect ferrous and nonferrous surfaces. Components that require tin plating are those commonly used in electronics, automotive, appliances, computer hardware, medical and food processing. Because tin has great ductility it allows a coated base metal sheet to form many different shapes without damaging the surface tin plating layer. Tin plating also provides sacrificial protection for copper, nickel, and other non-ferrous metals, with the exception of steel.
DiFruscia Industries offers lead free tin plating to preserve the solderability of underplated deposits and to offer corrosion protection and superior electrical conductivity where it’s needed.
