Question

Brass is an alloy of ______.

Options

• Cu and Sn

• Cu and Pb

• Pb and Sn

• Zn and Cu

Answer 1

Brass is an alloy of Zn and Cu.

Explanation:

Brass is a substitutional alloy made by melting together copper (Cu) and zinc (Zn). Copper serves as the base metal, while zinc is added to enhance the alloy’s strength, malleability, and corrosion resistance. The other options are incorrect because copper and tin (Sn) form bronze, while lead (Pb) and tin (Sn) are used to make solder.
