Oct 03, 2019018332Iron is the 4th most abundant element in the Earths crust. The Earths core is believed to be comprised primarily of iron. Pure iron is chemically reactive and corrodes rapidly, especially in moist air or at elevated temperatures. There are four allotropes of iron known as ferrites.Read More
Most aluminum in the crust is bound up chemically in ways that make it very difficult to separate, even with twenty-first century technology. Iron, on the other hand, comprises about five percent of the earths crust, and can be separated from its ore with little more than fire and charcoal. Other metals used by civilization are very rare.Read More
