Uses & Benefits
- It is also used in insecticides, hair dyes and as an anti-knocking additive for petrol. But all these are banned by the government as Lead metal is known for detrimental to health.
- 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.
