Tin plated sheet is made by immersing an iron piece in molten tin. Tin is a metal that is less active than iron. It is neither oxidized by air nor reacted with water, so it has a strong anti-corrosion ability. A thin layer of tin is plated on the iron sheet for good protection. However, once the coating is damaged and chemically corroded, because iron is more active than tin, iron will be lost as the negative electrode of the galvanic battery. The presence of tin will accelerate the corrosion rate of iron. Therefore, tin plate sheet electrolytic is different from white iron. The iron can be protected only when the coating is intact. Electrolite tin plate combines the strength and formability of steel with the corrosion resistance, solderability and beautiful appearance of tin in one material. Tin plated sheet has the characteristics of corrosion resistance, non-toxicity, high strength and good ductility.
