Facts
Interesting Facts
  • Strontium element is softer than Calcium.
  • Silvery Strontium turns yellow, if exposed to air.
  
  • 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
Uses & Benefits
  • Strontium metal is used to producing ferrite magnets as well as refining zinc.
  • By-product of nuclear reactors called Strontium-90 is a radioactive isotope; it is absorbed by tissues and destroys bone marrow and cancer growth.
  
  • 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.
