Answer 1

HERE IS YOUR ANSWER :-

Coils of electric irons and electric toasters are made of an alloy rather than a pure metal because alloys have more resistance and high melting point as compared to pure metal as they are mixture of different metals due to which they didn't melt even at very high temperature.

THANKS.

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.
