What are the three types of metals?

• A. Ferrous, Non-ferrous & Alloys
• B. Ferrous, Non-metals & Alloys
• C. Ferrous, Non-ferrous & Plastics
• D. Alloys, Ferrous & Non-ferrous

Answer: (A)

Metals are grouped into ferrous, non-ferrous and alloys. Ferrous metals contain iron, which often gives them magnetic properties and can lead to rust. Non-ferrous metals don’t contain iron, so they usually resist corrosion better and include metals like aluminum, copper, and zinc. Alloys are materials made by combining two or more elements, usually metals, to tailor properties—steel (iron plus carbon and other elements), bronze (copper plus tin), and brass (copper plus zinc) are common examples. The three categories together cover the main metal materials used in design and technology, which is why ferrous, non-ferrous and alloys is the correct grouping. The other options mix in non-metals or plastics, which aren’t metal categories.
