Tin has many uses.  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.Most window glass is made by floating molten glass on molten tin to produce a flat surface.  Tin salts sprayed onto glass are used to produce electrically conductive coatings.
