NEETChemistryClassification of Elements and Periodicity in Properties
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
- Ai, ii only
- Bii, iii only
- Ci, iii only
- 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.
