Which of the following alloy is used in making aircraft structures?
- Duralumin
- Brass
- Bronze
- Magainin
Hint:
Aluminum alloys are widely used in aircraft fuselages and other engineering structures and compounds in which light weight and corrosion resistance are highly desired.
The correct answer is: Duralumin
Aluminum alloys are widely used in aircraft fuselages and other engineering structures and compounds in which light weight and corrosion resistance are highly desired.
Duralumin (also called duraluminum, duraluminium, duralum, dural(l)ium, or dural) is a trade name for one of the earliest types of age-hardenable aluminium alloys. The term is a combination of Dürener and aluminium.
