answered-by-expert Expert Answer

Heating coils in electric home appliances are made of nichrome, an alloy of nickel, chromium, manganese and iron. The reasons for using nichrome in a heating coil are

i)     Nichrome has a high melting point.

ii)    The nichrome coil can remain in red-hot condition for a long time.

iii)   It has high resistance.
