Question

Brass is an alloy of _____ and _____ metals which shows significant ductility.

• A. $Cu$ and $Zn$
• B. $Pb$ and $Sn$
• C. $Zn$ and $Pb$
• D. $Sn$ and $Cu$

Answer 1

The correct option is A $Cu$ and $Zn$

Brasses are copper and zinc alloys with a wide range of engineering uses. The addition of zinc to copper raises the strength and gives a range of properties, and the brasses are a very versatile range of materials. They are used for their strength, corrosion resistance, appearance and colour, and ease of working and joining. The single-phase alpha brasses, containing up to about 37% zinc, are very ductile and easy to work, weld and braze.

Hence, the correct option is $A$
