Question

the heater element in an electric iron made of

Answer 1

Nichrome: Most heating elements use nichrome 80/20 (80% nickel, 20% chromium) wire, ribbon, or strip. Nichrome 80/20 is an ideal material, because it has relatively high resistance and forms an adherent layer of chromium oxide when it is heated for the first time.

Answer 2

Nichrome

Because of following reasons :-

1. Nichrome is an Alloy which has higher resistivity than pure metal.

2. It has high melting point and does not burn readily or oxidise
