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.
  
  • Magnesium aluminum alloy improves the mechanical strength and welding characteristics and hence it is used in aeroplane and car manufacturing.
  • It is also used to remove sulfur from the molten iron and steel.
