Question: 1 / 400

What is the primary component present in ferrous metals?

Aluminum

Iron

The primary component present in ferrous metals is iron. Ferrous metals are defined specifically by their iron content, which makes up a significant portion of their composition. This iron content is what gives ferrous metals their characteristic properties, such as strength and magnetism.

Ferrous metals, including steel and cast iron, are widely used in construction and manufacturing due to their durability and ability to withstand heavy loads. The presence of iron also affects other properties, including corrosion resistance, which can be influenced by the addition of various alloying elements. In contrast, the other options listed—aluminum, copper, and plastic—do not contain iron as a primary component and are categorized differently within the context of material science. Aluminum and copper are non-ferrous metals, while plastic is a synthetic material that does not contain metal at all.
