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.
  
  • Its ally with steel is used very tough and hence it is used in armor plates, axles, piston rods, tools and crankshafts.
  • Its oxide is used as pigments for glass and ceramics.
