Uses and Properties:

• Tin is a soft, pliable, silvery-white metal. 

• Tin is not easily oxidized and resists corrosion because it is protected by an oxide film. 

• Tin resists corrosion from distilled sea and soft tap water, and can be attacked by strong acids, alkalis and acid salts.

• It takes a high polish and is used to coat other metals to prevent corrosion, such as in tin cans, which are made of tin-coated steel

• Alloys of tin are important, such as soft solder, pewter, bronze and phosphor bronze

• A niobium-tin alloy is used for superconducting magnets.
