Interesting and Useful Facts about Iron thoughtco

Jan 11, 2019Iron is one of the most plentiful elements. It comprises about 5.6% of the earth's crust and almost all of the earth's core. The single largest use of iron is to make steel, an alloy of iron and a smaller amount of carbon. According to achaeological records from Anatolia, man has been producing steel for at least 4,000 years. Iron is a transition metal.
