Tin Applications
Solders, which are tin-lead alloys in different proportions depending on the purpose, consume one third of the produces tin. Alloy with 62% Tin and 38% Lead, is called eutectic of Sn-Pb system with minimal melting temperature. It is used in electronics. Other lead-tin alloys such as 30% Sn + 70% Pb, which have a broad solidifying zone, are used in pipelines welding as welding filler. Solders without lead are also used. Tin-copper (-antimony) materials are used as antifriction alloys (babbit, bronze) as bearing alloys. Contemporary tin-lead alloys contain 90-97% Sn with slight antimony and copper dopant for strengthening. Today's tin articles are quite safe.
Tin is used for protective and decorative coating immersing the article into the molten metal; however most articles are coated by tin alloys with lead, copper, nickel, zinc and cobalt are coated by electroplating.
