Alloys of iron: - Iron is a chemical element with the symbol Fe (Latin: ferrum) and atomic number 26. Iron is a group 8 and period 4 element. Iron is lustrous and silvery in color. It is soft, about 80 Brinell, relative to steel, which is about 140 Brinell. It is one of the few ferromagnetic elements.
Iron-56 is the second heaviest stable isotope produced by the alpha process in stellar nucleosynthesis, the heaviest being nickel-62; heavier elements require a supernova for their formation. Iron is the most abundant element in the core of red giants, and is the most abundant metal in iron meteorites and in the dense metal cores of planets such as Earth. Iron and iron alloys are also the most common ferromagnetic materials in everyday use.
