If silver is the best conductor of electricity, why is gold used in electronics instead?
In: Engineering
Gold doesnt rust and is very malleable (soft). This makes it ideal for the surface of connectors because it provides a large contact surface that doesn’t separate over time. In general you only need a very thin layer of gold to achieve this effect.
EDIT: since the plating is very thin, the relatively small difference in conductivity isn’t an issue.
