Interesting Facts
- In the list of most abundant element Tin is ranked 49th.
- Tin metal does not react with water as well as does not corrode in it.
  
- Manganese is an essential trace element in all forms of life.
- Manganese metal oxidizes very easily, but it does not fuse that easily.

Uses & Benefits
- Tin-niobium alloy is used for producing superconducting magnets.
-
Tin salt known as a tin II chloride, it is used as a mordant and as a reducing agent for dyeing calico and silk.
  
- This metal is very brittle hence it mostly not used as a pure metal, but its alloys are very useful
- Its alloy Manganese steel is extremely strong and used in railway tracks, safes, prison bars and riffle barrels.
