Question

A light and strong alloy is required for making the bodies of aircrafts. What should be its constituents?

Answer 1

A homogenous mixture of metal with another metal or a nonmetal results in the formation of an alloy. The properties of alloy differ from the constituent metals.

• A light and strong alloy required for making the bodies of aircraft is Duralumin.

Duralumin is an alloy of Aluminum, Copper, Magnesium, and Manganese. In duralumin, the composition of Aluminum, Copper, Magnesium, and Manganese is 95%, 4%, 0.5%, and 0.5% respectively. It is hard, strong as steel and very light. It is used in aeroplanes and spacecraft.
