Question

Which of the following is a ferrous alloy?

• A. Brass
• B. Steel
• C. Solder
• D. Magnalium

Answer 1

The correct option is B

Steel

The explanation for the correct option

(B) Steel

• Ferrous alloys are those that are composed mainly of iron ($\mathrm{Fe}$).
• Steel is an alloy of Iron ($\mathrm{Fe}$) and carbon ($\mathrm{C}$).
• Thus, steel is a Ferrous alloy.

The explanation for the incorrect options:

(A) Brass is an alloy of Copper ($\mathrm{Cu}$) and Zinc ($\mathrm{Zn}$). Thus, brass is a non-Ferrous alloy.

(C) Solder is an alloy of Tin ($\mathrm{Sn}$) and Lead ($\mathrm{Pb}$). Thus, Solder is a non-Ferrous alloy.

(D) Magnalium is an alloy of magnesium ($\mathrm{Mg}$) and Aluminum ($\mathrm{Al}$). Thus, Magnalium is a non-Ferrous alloy.

Hence, the correct option is (B).
