Uses
Uses & Benefits
- Yttrium metal is used in different alloys, as it increases the strength of aluminum Magnesium alloy. It is used for radar microwave filter.
- It is also used as a catalyst in ethene polymerisation.
- 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.
