1. Introduce
– A metal with good castability due to its excellent electrical conductivity, ductility, corrosion resistance, and easy melting properties
– Metal that becomes a superconductor at 3.72K
→ Almost the first metal whose superconducting properties were investigated and in which the Meissner effect was first discovered
– Mostly used as an alloy or compound with other metals, tin’s greatest applications are as a plating to prevent corrosion of alloys or other metals, and as a solder used to connect metal tubes and circuits in electronics
– Sn alloying element effects: low melting point, corrosion resistance
2. Property
– Oxidation and corrosion resistance, ductility, malleability, excellent castability
