The term PLATING METAL can be broken down into two words, the first being 'TIN, ' which is a three-letter metal. TIN is a soft, silvery-white metal that is malleable and ductile. It is most commonly used in alloys, such as bronze and pewter, and is also used to coat other metals to prevent corrosion. TIN plating is often used in the automotive and aerospace industries to protect parts from corrosion and wear.
