What type of metals contain no iron?

• A. Non-ferrous
• B. Ferrous
• C. Alloys
• D. Steel

Answer: (A)

Metals that do not contain iron are called non-ferrous. This category is defined by the absence of iron, which also often means they’re not magnetic and resist corrosion differently than iron-containing metals. Examples include aluminum, copper, zinc, nickel, and titanium, which are prized for properties like light weight, good conductivity, or corrosion resistance. In contrast, ferrous metals contain iron, with steel being a common example, so they aren’t non-ferrous. While alloys can be either ferrous or non-ferrous depending on whether iron is part of their composition, the key distinction here is the absence of iron, which makes non-ferrous the correct choice.
