Why is gold used in electronics when it is expensive compared to other metals like copper and silver?
There are some electronic components that quite simply have to be made from gold because of its unique combination of properties. Gold has excellent thermal and electrical conductivity, so it makes efficient wires and contacts in electronics, transporting electrical signals efficiently and conducting heat away from critical components. With its high corrosion resistance, the gold found in electronic contacts remains free from tarnish or oxidation. This ensures that reliable electrical connections can be made, even after thousands of operations.
