Which of the following alloy contain Al, Cu, Mg and Mn?
- A Babbitt metal
- B Stainless steel
- C Spiegeleisen
- D Duralumin
Answer & Solution
Correct Answer
(D) Duralumin
Step-by-step Solution
Detailed explanation
(B)
Duralumin is an alloy, a trade name given to the earliest types of the age hardenable aluminum alloys.
It is an alloy made up of \(90 \%\) aluminum, \(4 \%\) copper, \(1 \%\) magnesium and \(0.5 \%\) to \(1 \%\) manganese. It is a very hard alloy.
Option B is correct.
