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.
  
  • Ytterbium metal is used in memory devices and tuneable laser.
  • It is also used as industrial catalyst as the other catalysts are too toxic and polluting.
