Uses
Uses & Benefits
  • Europium metals main uses is in the printing of euro banknotes. These notes glow red under UV light.
  • It is used in low energy light bulbs.
  
  • Tin and bismuth alloys have a very low melting point and hence it is used in fire detector and the fire extinguishers. It also used in electric solders and fuses.
