If the conductivity of mercury is 1, the conductivity of copper is 57, and the conductivity of silver is 59, which is good. Therefore, silver is often used to manufacture high-sensitivity physical instrument components, various automated devices, rockets, submarines, computers, nuclear devices, and communication systems.
