Copper alloys have low thermal conductivity but high electrical conductivity.

A. True

B. False

I got this question in semester exam.

Origin of the question is Copper Alloys in portion Foundry Introduction & Materials of Casting-Forming-Welding II

Right answer is B. False

Explanation: Copper alloys have high thermal conductivity as well as high electrical conductivity. Due to high electrical conductivity, they are used in making of electric wires, in motor winding etc. And high thermal conductivity of copper alloys useful in making of heat exchangers, in piping of power-plants, air conditioning, refrigerators etc.
