Uses
Uses & Benefits
  • Tungsten and its alloys are used in high-temperature applications like welding electrodes, high-temperature furnace, etc.
  • Tungsten carbide is very hard and used in metal working, mining and petroleum industry.
  
  • 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.
