Tin ingots are a kind of commodity tin cast into ingots. After partial refining, they still contain a small amount of different impurities (such as copper, lead, iron or arsenic). They are solid tin different from tin plates. They can be used as coating materials and have a wide range of uses in food, machinery, electrical appliances, automobiles, aerospace and other industrial sectors.
