Which of the following metals is classified as ferrous?

• A. Aluminum
• B. Mild steel
• C. Brass
• D. Copper

Answer: (B)

Mild steel is classified as a ferrous metal primarily because it contains iron. The term "ferrous" is derived from the Latin word "ferrum," meaning iron. Ferrous metals are known for their magnetic properties and higher strength, which can be significantly influenced by their iron content. Mild steel, specifically, is primarily composed of iron and a small percentage of carbon, making it both strong and ductile, suitable for various applications in construction and manufacturing. In contrast, aluminum, brass, and copper are classified as non-ferrous metals. These metals do not contain significant amounts of iron, which contributes to their different physical and chemical properties, such as resistance to corrosion and lighter weight compared to ferrous metals. Understanding the classification of metals into ferrous and non-ferrous categories is crucial in welding and material selection, as it directly affects welding techniques and the behavior of metals during heating and cooling processes.
