Uses
Uses & Benefits
  • It has corrosion resistance and hence it is used to plate other metals.
  • Its alloys are very useful; Nichrome alloy is used in the hot coil of toasters and electric oven.
  
  • 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.
