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.
