What is the difference between ferrite and iron? | WikiDiff

Ferrite is a see also of iron. As nouns the difference between ferrite and iron is that ferrite is the interstitial solid solution of carbon in body-centered cubic iron while iron is (uncountable) a common, inexpensive metal, often black in color, that rusts, is attracted by magnets, and is used in making steel. As a adjective iron is (not comparable) made of the metal iron.
