I don't know! But, metal fillings can contain Mercury. It can leach into your blood stream. My mouth is full of them. If I had the money I would have them replaced with the newer white filling.
dont know too much about this but I know copper is a popular one, but now a days they are using light and fiber to communicate over wires. The phiber is encased with a mirror type material that is shetthed around the fiber and a light is sent trough the wire, the light bounces of the mirror coating until it reaches the other side. they use a serious of flashes, on/off of the light to communicate 0 1's as data down the phiober. then they use different frequencies of light so they can send multiple 0 or 1's down the fiber. I know this is off topic but oh well
Copper is the most used metal in communications. Right now the cost is volitile due to demand by third world countries for infastructure. In small components there is gold and titanium as well as some exotics being used for plating to increase reliability and low resistant throughput.
There are a number of metals used for communications. They tend to be used in different places depending on the application. I would guess that the most commonly used metal is copper for wiring, but you'll also find lead and tin used for solder, gold for contacts and connectors. Once you get inside the actual electronics, you'll find semiconductors like germanium, gallium and arsenic as well as conductors including copper and aluminium. The source below also has tables for resistance for various metals in wire form.
