Which statement is true about nonferrous metals compared to ferrous metals?

• A. Non-ferrous metals contain majority iron while ferrous metals do not contain iron.
• B. Ferrous metals contain majority iron while non-ferrous metals do not contain iron.
• C. Both contain the same iron content.
• D. Iron content is irrelevant to classification.

Answer: (B)

Ferrous versus nonferrous is defined by iron content. Ferrous metals contain iron as a major component, while nonferrous metals do not have iron as their primary constituent. That makes the statement true: ferrous metals have majority iron, while nonferrous metals do not contain iron as their main element. This classification helps explain typical behavior: ferrous metals (like steel and cast iron) are often magnetic and can rust unless alloyed or protected, whereas common nonferrous metals (such as aluminum, copper, and zinc) are not iron-based and usually resist rusting, offering different properties like lighter weight or better electrical conductivity.
