Which of the following materials is classified as a "ferrous" material?

Aluminum
Copper
Steel
Plastic

The correct answer is: Steel

Ferrous materials are those that contain iron. Steel, being primarily composed of iron, falls into this category. Its ferrous nature significantly contributes to its properties, such as strength and magnetism, making it a key material in construction and manufacturing applications. In contrast, aluminum and copper are non-ferrous metals, meaning they do not contain iron. They possess different characteristics, such as being lighter and more resistant to corrosion, but lack the magnetic properties associated with ferrous materials. Plastic, while not a metal, is also a non-ferrous material, as it does not contain iron and exhibits completely different physical and chemical properties suitable for various applications. Therefore, steel is classified as a ferrous material due to its iron content.
