Why are the coils of electric toasters and electric irons made of an alloy rather than a pure metal?

Answer

The resistivity of alloys is much more than the resistivity of pure metals.

Hence, the resistance produced by alloys is higher than that produced by its constituent metals

Also, Alloys do not burn readily even at high temperatures.

For this reason, they are used in electrical heating devices like electric toasters and electric irons.
