Uses

Uses & Benefits
  • Tantalum metal is mainly used in the manufacturing of electron components. Its Oxide layer acts as an insulator.
  • Tantalum metal is also used in surgical transplant like replacement of bone, skull plates and as a woven gauze.
  
  • 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.
