What metal best conducts cold?

Answer 1

None. Metals do not stay cold.

Metals are very good conductors of heat and so when we touch them they FEEL colder (or hotter) than when we touch other materials that are not as good conductors of heat at the same temperature as the metal. If both are colder (or hotter) than our body temperature, the metal will always feel colder (or hotter) than the other material, because it is able to conduct heat out of (or into) the part of our body in contact with the metal faster than the other material is able to.

Answer 2

It is not quite correct to talk about conducting "cold" or "hot". Thermal conduction is always measured between different temperatures, one colder, one warmer. It is the thermal conduction of energy between, tending to reduce the difference in temperatures.

The metal with the best thermal conduction is silver.There are two different types of conduction: thermal and electrical conduction. Metals have thermal and electrical conduction in close proportion, unlike many non-metals. Silver has the highest thermal and electrical conductivity of any metal or alloy. However there are non-metal materials with far higher thermal conductivity.
Metal is not good for keeping anything cold. For that you need an insulator.

Answer 3

Silver conducts heat and electricity better than any other metal. But the industry mainly uses copper because it is cheaper and heat spreads more evenly.

Answer 4

It is supposed that the cause is the electron-phonon interactions in metals, more important at high temperatures.

Answer 5

Copper is a good thermal conductor and can efficiently transfer cold temperatures. It is often used in refrigeration and air conditioning systems to transport chilled air or liquids.
