Non-ferrous metals are defined as which of the following?

• A. Metals containing iron.
• B. Metals that do not contain iron.
• C. A mixture of two or more metals.
• D. Non-metals.

Answer: (B)

Non-ferrous metals are metals that do not contain iron. This matters because metals with iron (ferrous metals) can rust and are often magnetic, while non-ferrous metals avoid these issues and typically offer other advantages such as lighter weight, better corrosion resistance, or superior electrical and thermal conductivity. Examples include aluminium, copper, zinc, tin, lead, and the precious metals. The definition focuses on excluding iron, not on being alloys or on being non-metals.
