Interesting Facts
- Tungsten element has the second highest melting point.
- Pure tungsten can easily cut down with the help of hacksaw.
- Bismuth metal is soluble and reacts with concentrated nitric acid.
- It oxides are used as a yellow pigment in paint. Bismuth chloride oxide BiClO gives a pearly texture to cosmetics.

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.
- Tin and bismuth alloys have a very low melting point and hence it is used in fire detector and the fire extinguishers. It also used in electric solders and fuses.
