Why is gold used in cell phones?

Answer 1

golds the the 3rd best electrical conductor (silver is the best, then copper).

Gold is the best material to use for the little connectors that connect the various parts of a cell phone together, because the only materials with better electrical conductivity (silver is the best, followed by copper) quickly corrode in air, leaving the connectors with a thin layer of terribly low conductivity corrosion products.

Answer 2

A very small amount of gold is used in many cellphones for connection between components. Gold does not tarnish and increase it's resistivity easily and makes it a perfect element for this application. Silver can be used in less expensive cellphones, but you get what you pay for in many applications.

Answer 3

That would depend on where the gold is used. If it is on the outside it is there to make the phone look bling. If it is on the inside, it is probably being used to ensure that the electrical contacts do not corrode over time.

Answer 4

Gold is on the battery contacts and that oh-so-disposable SIM card.

Answer 5

Silver is a vital component of circuits. Circuits are used in many electronics, from mobile phones to computers, making silver an important part of the manufacturing process.

Answer 6

As it has the best connectivity.
