Ferrous metals mainly consist of metals which have a magnetic effect to it. This steel and iron is composed of carbon. These metals are melted down and recycled into many things. Ferrous metals is by far the most-recycled material in the world.
Ferrous (Fe2+), in chemistry, indicates a divalent iron compound (+2 oxidation state), as opposed to ferric, which indicates a trivalent iron compound (+3 oxidation state). This usage has mostly been deprecated, with currentIUPAC nomenclature having names containing the oxidation state in bracketed Roman numerals instead, such as iron(II) oxide for ferrous oxide (FeO), and iron(III) oxide for ferric oxide (Fe2O3).
Outside chemistry, ferrous is an adjective used to indicate the presence of iron. The word is derived from the Latin word ferrum (“iron”). Ferrous metals include steel and pig iron (with a carbon content of a few percent) andalloys of iron with other metals (such as stainless steel). Manipulation of atom-to-atom relationships between iron, carbon, and various alloying elements establishes the specific properties of ferrous metals.
