Iron is a metal.
It can be dug up straight out of the ground and used without much trouble. This allowed early man to discover it early, during the Iron Age in fact. Iron weapons were far better than ones made of softer metals, like bronze. A swordsman with an iron sword could cut a bronze sword in half if his enemy tried to block him with it. Iron was also used in construction. The Eiffel Tower and Golden Gate Bridge are both made of iron. The strength of iron meant that engineers could build much bigger structures with it than with stone. When iron corrodes it is called rust. Corrosion on other metals is not called rust.
Iron is also a component of red blood cells in the form of hemoglobin.
Something made of, or largely composed of, iron can be described as irony.
Found in numerous Bible quotes: Iron sharpens iron. --Proverbs 27:17
