Question

in the electric equipment producing heat example iron, electric heater, boiler, toaster etc, and alloy such as nichrome is used, not pure metals​

Answer 1

Answer:

It is so because pure metals may melt at high temperatures. But nichrome doesn't.So it is used in in pure metal's stead.

Answer 2

$\huge\text{\underline{Answer}}$

Heating devices are mainly made up of Nichrome wire because of the following factors :-

1. It does not get easily oxidised readily at high temperatures.
2. It has high resistivity than pure metals.
3. It has high melting points.

These are some reasons for using alloy or nichrome wire for heating elements .

If we choose pure metals having Very low resistivity,low melting point and oxidised easily .

That's why instead of pure metals we should use alloy or nichrome wire for heating elements in devices such as heater and toaster.
