Ferrous metal refers to any metal that contains iron. The category includes a wide range of materials, with iron being the predominant element. The term ferrous originates from the Latin word “ferrum,” which means iron. The most common ferrous metal is steel. Its mechanical properties make it valuable in numerous industrial applications. Ferrous metals are celebrated for their high strength, durability, and ability to bear high temperatures, making them suitable for demanding environments. The magnetic character of ferrous metals is another distinguishing feature attributed to the presence of iron. Despite the advantages, ferrous metals, which have a high iron content, are susceptible to rust and corrosion when exposed to moisture and oxygen. For this reason, we need protective measures such as coatings or alloys to enhance their oxidation resistance. These metals are the backbone of a number of industries, like construction, automotive, machinery manufacturing, and infrastructure development. Its strength, durability, and magnetic properties make it indispensable in various applications where reliability and performance are paramount.
