Ferrous metals contain which element?

• A. Aluminum
• B. Copper
• C. Iron
• D. Titanium

Answer: (C)

Ferrous metals are metals that contain iron. The word comes from ferrum, the Latin for iron, so iron is the defining element in ferrous materials. That’s why iron is the correct answer. Common ferrous metals include steel and cast iron, which are often magnetic and can rust if not protected. The other elements listed—aluminium, copper, and titanium—do not contain iron, so they are non-ferrous.
