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

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

 

Answer:-

Coils of electric toasters and electric irons made of an alloy rather than a pure metal because the resistivity of an alloy is higher than the pure metal. Also at high temperatures, the alloys do not melt easily.
