Description and Uses
Tin has a long, colorful history. The extraction and use of tin began during the Bronze Age around 3000 BC when early craftsmen discovered that bronze – a noncorrosive metal that is extremely hard and strong enough to be used for spears, swords, arrows, and other especially important objects at that time – could be produced by smelting tin with copper. Tin is also the primary constituent of pewter. Long ago, people developed the belief that trace amounts of tin seemed to help prevent fatigue and depression, and that drinking out of tin cups could help combat these ailments. Tin toys, tin coated cans, and tin roofs have also enjoyed great popularity in the past.
Tin is used in tin plating; soldering; dental alloys; collapsible tubes; in the production of tin salts.
