The presence of impurities can affect the malleability of a metal in different ways.

1. If the impurities are such that they allow the layers of the metal to slide over each other more easily, then they can make the metal more malleable. This is because malleability is the ability of a metal to be hammered or rolled into thin sheets, and this process is easier if the layers of the metal can slide over each other easily.

2. However, if the impurities are such that they prevent the layers of the metal from sliding over each other easily, then they can make the metal less malleable. This is because the process of hammering or rolling the metal into thin sheets becomes more difficult if the layers of the metal cannot slide over each other easily.

3. It's also possible that the impurities have no effect on the malleability of the metal. This would be the case if the impurities do not affect the ability of the layers of the metal to slide over each other.

So, the effect of impurities on the malleability of a metal can vary depending on the nature of the impurities.
