As copper is an excellent conductor of heat, it’s good for heat exchangers, heat sinks, and even saucepan bottoms….Which Metals Conduct Heat The Best?

Copper has more number of free electrons which are responsible for carrying electric current. Iron has comparatively less number of free electrons thus it is inferior to copper in terms of conductivity.

Copper

Thus, copper is a lattice of positive copper ions with the movement of free electrons among them. Due to movement of electrons freely through the metal, they are also known as conduction electrons. The presence of these conduction electrons makes the copper a good conductor of electricity and heat.

The simple answer is copper atoms are pack tightly together along with the free electrons .. the two together allow copper to be a good conductor of heat and electricity .. glass does not have these properties and is considered a good insulator .

Titanium and its alloys have extremely low thermal conductivity. It also tends to be extremely resistant to corrosion. Stainless steel is also a good insulator, though not as good as Ti.

Lead

Lead is the poorest conductor of heat. A good insulator is obviously a poor conductor. An interesting fact is that poor conductors of electricity are also poor heat conductors. Wood is a much better insulator than copper.

Lead is a metal that is a bad conductor of heat.

An insulator is a material that does not allow a transfer of electricity or heat energy. Materials that are poor thermal conductors can also be described as being good thermal insulators. Feather, fur, and natural fibers are all examples of natural insulators.

Lead being metal is a bad conductor of electricity and heat. Compared to other metals, lead is a poor conductor of heat while gold, silver, platinum are good conductors of heat. Lead is malleable, it is easily bent, soft, dense and a poor conductor of electricity.

Bismuth and tungsten are two metals which are poor conductors of electricity. Dear friend, Tungsten and Bismuth are metals which are poor conductors of electricity. Stainless Steel is a poor conductor because it has an alloy structure.

Copper, steel and iron being metals have free electrons available for conduction. Water is a non-metals and does not have free electrons for conduction. Hence it is a bad conductor.

Conductors conduct electrical current very easily because of their free electrons. Insulators oppose electrical current and make poor conductors. Some common conductors are copper, aluminum, gold, and silver.

A poor conductor means that the substance will not easily conduct heat or electricity (or both) as easily as a conductor. Most metals, such as copper, are good conductors, whereas most other non-metal materials are bad conductors, or insulators. For example, sand is a poor conductor of heat and electricity.

Materials that allow heat to pass through them easily are called good conductors of heat. Materials that do not conduct heat as easily and quickly as metals do are bad conductors.

Difference between Good Conductor and Bad Conductor of Electricity

Conductors are materials that permit electrons to flow freely from particle to particle. Conductors allow for charge transfer through the free movement of electrons. In contrast to conductors, insulators are materials that impede the free flow of electrons from atom to atom and molecule to molecule.

Most electrical wire is covered in a rubber or plastic coating called insulation. The purpose of insulation covering the metal part of an electrical wire is to prevent accidental contact with other conductors of electricity, which might result in an unintentional electric current through those other conductors.
