Question

Alloys are used as an electrical heating device rather than pure metals. Give reason.

Answer 1

• Alloys are obtained by the constituent mixing of metals with other metals or nonmetals.
• The properties of alloys are different from the constituent metals that are mixed to obtain alloys.
• It is observed that the melting point of alloys is higher than the parent metal.
• Due to the high melting point and high resistivity alloys are used mainly in an electrical heating devices than parent metals.
• An example of an alloy that can be used in an electrical heating device is Nichrome.
• Nichrome alloy is the combination of Nickel $\left(\mathrm{Ni}\right)$ and Chromium $\left(\mathrm{Cr}\right)$.
