Tin plating applications include corrosion protection, to facilitate soldering, to improve anti-galling characteristics, and for use as a stop-off barrier in the nitriding of high-strength steels. Color is gray-white, and ranges from matte to bright in appearance depending on the process used. Tin deposits are soft and very ductile, however, are not suitable in low temperature applications.
