If silver is the best conductor of electricity, why is gold used in electronics instead?
In: Engineering
Gold is used because of it’s other physical properties, not just it’s conductivity. Gold doesn’t corrode (oxidize), so it’s commonly used for things that get plugged it – faces of connectors, pins, etc. Most other metals develop an oxide layer which degrades the electrical signal. A secondary use of gold is for connecting silicon to metal using a process called wire bonding.
