Solution
Duralumin is expected to be less malleable than aluminium. This is because duralumin is an alloy, which means it is a mixture of several metals, including aluminium, copper, and other elements. The presence of these other elements in the alloy can disrupt the regular arrangement of atoms in the metal, making it harder for the layers of atoms to slide over each other. This makes the alloy less malleable than the pure metal. On the other hand, aluminium is a pure metal and its atoms are arranged in a regular pattern, making it easier for the layers of atoms to slide over each other, thus making it more malleable.
