Copper has a very high thermal conductivity and is much cheaper and more available than silver, which is the best metal of all for conducting heat.

Why metal conducts heat the best?

A: Kelly- The reason metals conduct heat so well is that the electrons in them can move around easily, and they can carry heat from one part to another. (Those are the same electrons that carry electricity around, making metals good electrical conductors.)

What is the most conductive material on the planet?

As a result, silver is by far the most conductive metal on Earth. This is because silver only has one valence electron. In addition, this single electron is free to move around with little resistance. As a result, metals like silver and copper are a few of the metals with this particular characteristic.

What is the best conductor on earth?

The most electrically conductive element is silver, followed by copper and gold. Silver also has the highest thermal conductivity of any element and the highest light reflectance.

Is graphene more conductive than silver?

At room temperature, graphene has slightly better conductivity than silver. However, graphene is a 2-dimensional conductor, and does not conduct well between the graphene layers.
