Facts
Interesting Facts
- Dysprosium acts stable in air at room temperature.
- Dysprosium behaves very much like paramagnetic metal.
- Manganese is an essential trace element in all forms of life.
- Manganese metal oxidizes very easily, but it does not fuse that easily.

Uses
Uses & Benefits
- Dysprosium metal is highly reactive due to which it pure form is not as usual as its alloy.
- Thi metals alloy is used in magnate as it is resistance to high temperature.
- 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.
