All metals are conductors of electricity, however, each type of metal has different conductivity level, and thus, some are more conductive than the other. For example, the Copper metal is one of the most common, if not the most common metal used to conduct electricity. It is a highly conductive material that is commonly seen as components in electrical wirings.
However, copper is not the most conductive metal on the planet. The truth is that silver is the most conductive metal with more or less 105% conductivity level versus the copper’s 100%. On the other hand, the problem with silver is that it can be tarnished, which can cause problems when used in electrical devices.
