Metal as Electrical Conductor, Not Thermal
Date: Spring 2012
Name a metal which is good electric conductor, but a bad thermal conductor?
To my knowledge, there are no metals that are good electrical
conductors, but poor thermal conductors. In metals, electrical
conductivity and thermal conductivity tend to go hand in hand.
Interestingly, there are substances that are the reverse of what you are
asking; that is, they are excellent thermal conductors, but are electrical
insulators. The most well known is diamond, which is a better thermal
conductor than any metal, yet diamond is an electrical insulator.
