A thin layer of tin plating on iron can be good protection effect. But coating electrochemical corrosion occurs, once they are damaged due to iron lively than tin, iron will serve as a galvanic anode oxidation reaction and loss, the existence of tin will speed up the corrosion rate of iron, tin and tin is different, so it can only under the condition of the coating in good condition is to protect the action of iron.
