Question

8. Why alloys are used rather than pure metals in heating devices?
​

Answer 1

As we know alloys have high resistivity and high melting point as compared to pure metals. So alloys cannot easily burn or oxidize at higher temperature. Now as we want higher temperature in heating devices so we use alloys in heating devices. ... Alloys are, for example: Nichrome, generally harder than pure metals.
