Interesting Facts
- Dysprosium acts stable in air at room temperature.
- Dysprosium behaves very much like paramagnetic metal.
- Iron is not always magnetic in nature, its allotrope are ferromagnetic and the B allotrope is nonmagnetic.
- The blood consists Iron in hemoglobin molecules to transfer Oxygen in the body.

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.
- Iron metal alloy steel is used in the application of civil engineering and manufacturing.
- Alloys of iron with nickel, vanadium, chromium, tungsten and manganese have very useful properties.
