Many materials are both electrical and thermal conductors or insulators. However, there are exceptions, so don't assume just because a sample conducts (insulates) one form of energy that it behaves the same for other forms! Metals typically conduct both heat and electricity.
Electricity - Electricity - Conductors, insulators, and semiconductors: Materials are classified as conductors, insulators, or semiconductors according to their electric conductivity. The classifications can be understood in atomic terms. Electrons in an atom can have only certain well-defined energies, and, depending on their energies, the electrons are said to occupy particular energy levels.
Iron is not as good a conductor, but if we talk about iron conductivity in general, it can be considered a fairly good conductor of electricity with it being 17% conductive. Its resistance is 9.7 micro-ohm cm. Iron, being a metal, also has free electrons in its valence shell that, with some force from the attached battery, start flowing through it.
The thermal conductivity and electrical resistivity of uranium are 27 W/m and 28.10-8 ohm.m respectively. In case of metals, a good conductor of heat is also a good conductor of electricity. This is not true for most of the nonmetallic substances. For instance, Diamond is a much better conductor of heat than copper, but it is an electrical ...

Metal as a Conductor of Heat and Electricity What makes one metal conduct heat and electricity better than another metal? Answer from Ken Hook, LAKE Science Collaborative Content Cadre Member and Science Teacher at Clear Lake High School I found this information on the Internet, and I think it explains fairly clearly for such a complicated subject.
Before we study this chapter, let's look at what are good and bad conductors of electricityGood Conductor of ElectricityThose materials which allow electricity to pass through them are called good conductors of electricityExampleSolids like Copper, Aluminium conduct electricityLiquids like Tap Water
An electrical conductor is an electric charge carrier (electrons) that move easily from atom to atom with the application of voltage. Conductivity is the ability to transmit electricity or heat. Good conductors are copper, gold, steel, aluminium, brass etc.
A conductor is a substance in which electrons can move freely from one atom to another. Can We Help with Your Assignment? Let us do your homework!

metals have electrical resistance. metals get hot when a current flows through them. Good Thermal Conductivity. Copper is a good conductor of heat. This means that if you heat one end of a piece of copper, the other end will quickly reach the same temperature. Most metals are pretty good conductors; however, apart from silver, copper is the best.
