Uses
Uses & Benefits
- 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.
- 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.
