5 Uses
5.1 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.
- This metal is very brittle hence it mostly not used as a pure metal, but its alloys are very useful
- Its alloy Manganese steel is extremely strong and used in railway tracks, safes, prison bars and riffle barrels.
