Facts
Interesting Facts
  • The main source of Cobalt is as a by-product of copper and nickel metal mining.
  • Cobalt metal can be obtained from other elements like Oxygen, Sulfur and Arsenic.
  • It s also used in electroplating process as it exhibits anti cession properties.
  
  • 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.

Uses
Uses & Benefits
  • Its alloys with aluminum and nickel are used to make powerful magnets.
  • Few other alloys exhibit high-temperature strength and hence they are used in Turbines of Jet and Gas engine.
  
  • 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.
