Question

why are the conductors of electric heating device such as bread toasters and electric iron made of an alloy rather then a pure metal?​

Answer 1

Answer:

Alloys are used in heating devices because the have melting and boiling point.

Alloys also provide high resistance which produces heat in the device.

Answer 2

Answer:

The resistivity of an alloy is higher than the pure metal. Moreover, at high temperatures, the alloys do not melt readily. Hence, the coils of heating appliances such as electric toasters and electric irons are made of an alloy rather than a pure metal.
