Tin is best known for its use in the manufacture of tin cans. It is most commonly seen as the outer layer on tin-plate or tin cans. It does not tarnish in the air, and protects iron only by excluding oxygen from the iron. This is in contrast to galvanizing where the protection by zinc is due to its higher activity than iron. Since tin is an expensive metal and tin is usually recovered from scrap tin-plate.
Tin is a popular alloying agent used in the manufacture of solders for electronic components.
C. Pure lead melts at 327 o C and pure tin at 232 o C. Bronze that contains tin is very resistant to corrosion and is similarly used for castings, especially for marine propellers and other ship fittings. Bronze is also used for large statues and bells.
