The tin-plating process is used extensively to protect both ferrous and non ferrous surfaces. Tin is a useful metal for the food processing industry since it is non-toxic, ductile and corrosion resistant. The excellent ductility of tin allows a tin coated base metal sheet to be formed into a variety of shapes without damage to the surface tin layer. It provides sacrificial protection for copper, nickel and other non-ferrous metals.
Tin is also widely used in the electronics industry because of its ability to protect the base metal from oxidation thus preserving its solder ability. Process under the Standard ASTMB545.
