Match List – I with List – II and select the correct answer by using the codes given below the list: List – I (Alloy) List – II (Constituent)  (a) Brass  (i) Cu and Sn  (b) Bronze   (ii) Al, Cu, Mg and Mn  (c) Duralumin  (iii) Al and Mg  (d) Magnellium  (iv) Cu and Zn Correct Answer (a) - iv, (b) - i, (c) - ii, (d) - iii

Explanation:

  • Magnalium is an aluminium alloy with 1.5 to 2% magnesium and small amounts of copper, nickel and tin. 
  • Bronze is an alloy consisting primarily of copper and about 12–12.5% tin.
  • The main alloying constituents in Duralumin are copper, manganese, magnesium and aluminium.
  • Brass is an alloy of copper and zinc.

So, the correct match are

Brass: Cu and Zn

Bronze: Cu and Sn

Duralumin: Al, Cu, Mg and Mn

Magnellium: Al and Mg
