the answer is potassium.
Heating element is the main part of the ironbox which gets heated as current passes through it. We have to use the material for heating element with features such as: 1) high melting point 2) high specific resistance 3) not easily oxidised. (most important point) Hence the alloy NICHROME ( nickel and chromium) is used for heating element because it is not oxidised even at high temperatures.
