What is the importance of 'TIN'?

Answer 1

Tin is a silvery, malleable, "poor" metal and is not easily oxidized in air, it is used to coat other metals to prevent corrosion. The first alloy used in large scale since 3000 BC was bronze, an alloy of tin and copper. After 600 BC pure metallic tin was produced. Pewter, which is alloy of between 85 % and 90 % tin with the remainder commonly consisting of copper, antimony and lead, was used for knives, forks and spoons from the Bronze Age until the 20th century. In modern times tin is used in many alloys, most notably tin/lead soft solders, typically containing 60% or more of tin. Another large application for tin is corrosion-resistant tin plating of steel. Due to its low toxicity, tin-plated metal is also used for food packaging, giving the name to tin cans, which are made mostly out of aluminum or tin-plated steel.
