Uses
Uses & Benefits
  • Actinium metal has a great source of alpha rays but it is hardly used outside research purpose.
  
  • 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.
