Which of the following alloys are correctly matched with their uses? (i) Li / Mg armour plates (ii) Cu / Be high strength springs (iii) Mg / Al aircraft construction

Options

  1. Ai, ii only
  2. Bii, iii only
  3. Ci, iii only
  4. Di, ii, iii

Correct answer

D. i, ii, iii

Step-by-step solution

Li and Mg being hard metals are used as an alloy in armour plates. Cu - Be alloy is used in high-strength springs due to ductility of Cu . Mg - Al alloy is used in aircraft construction as Al is a versatile metal.
