Detailed Solution

The above statement is True.
An electric toaster and iron coils are manufactured of an alloy rather than a pure metal for the following reasons:
An alloy's resistivity is greater than that of pure metal.
The alloys do not oxidise at high temperatures.
Alloy is difficult to melt and distort.
Alloys have a high coefficient of resistance at low temperatures.
As a result, heating coils in products such as electric toasters and irons are built of an alloy rather than a pure metal.
