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.

Answer 2

Answer:

• Alloys are used in electrical heating devices rather than pure metals because the resistivity of an alloy is more than the resistivity of a pure metal. Moreover alloy does not burn (or oxidize) easily even at higher temperature
