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.
  
  • 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.
