Tin is widely used in the production of solder for electronic circuits due to its low melting point and good conductivity when alloyed with lead or as lead-free alternatives. It serves as a protective coating for steel in tinplate, commonly used in food packaging like cans, preventing corrosion and extending shelf life. Tin is a key component in bearing alloys, such as Babbitt metal, valued for its durability and resistance to wear in machinery. It is also used in the manufacture of glass, where molten tin provides a flat surface for float glass production. In chemicals, tin compounds act as catalysts in polymer production, especially in silicones and polyurethanes. Additionally, tin oxide is used in ceramics and sensors for its electrical and optical properties.
