Iron is a chemical element with the symbol Fe (from Latin: Ferrum). It is, by mass, the most common element on Earth, forming much of Earth’s core.
Iron alloys, such as steel, stainless steel, and cast iron, are the most common industrial metals because of their mechanical characteristics and economic cost.
Humans started to master iron as helpful material for making tools in Eurasia as early as 2000 BCE. In some regions, iron tools and weapons began to displace copper only around 1200 BCE.« Back to Glossary Index
