2 Facts

2.1 Interesting Facts

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.

Galena mineral contains almost 87% of Lead metal in it, Galena is sulfide mineral.
The best available source of Lead metal today is by recycling automobile batteries.

3 Uses

3.1 Uses & Benefits

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.

It is also used in insecticides, hair dyes and as an anti-knocking additive for petrol. But all these are banned by the government as Lead metal is known for detrimental to health.
