iron because :
​

Answer 1

Answer:

Because of its high resistivity nichrome wire is used in heating devices.

Explanation:

Also resistivity is directly proportional to resistance. So it's resistance will be more which causes heating

Answer 2

Answer:

alloys are used for making the coils electric toasters and electric irons because alloys are higher melting point than pure metals
