Question

Why are the conductors of electric heating devices such as bread toasters and electric irons made of an alloy rather than a pure metal?

Answer 1

Hint:The metals are intrinsic while alloys are doped of two or more metals that have been melted together. The metals and alloys are easy to distinguish from non-metals because they are usually shiner, heavier and harder than most materials and they are excellent conductors of heat and electricity.

Complete Step by Step Answer:
The electrical heating devices such as toaster or electric iron is made of an alloy rather than pure metal because if electrical heating devices are made by pure metal then the metal melts easily when heat is increased and pure metal gets corroded easily. The alloy does not corrode easily and its melting point is high, so that we are using the alloys rather than a pure metal.

Note:The alloys offer high strength, excellent fabric ability and outstanding corrosion resistance. These desirable properties are due to the combination of elements that make up the alloy as an electric heating device.
