Ferrous metal is a term that is used for any metal that has iron as its main component in its composition. There is a broad range of metals that fall into this category. Examples include: wrought iron, cast iron, steel, and stainless steel. These metals usually have good mechanical properties, like high strength and durability. They are also known to have magnetic properties and most are prone to rust when exposed to moisture, due to the iron content. These metals are highly recyclable which contributes to their popularity in many applications, especially in the industrial sector. Ferrous metals are also commonly used in the construction and manufacturing industries.
