Common Metals Used in Electrical Wires and Cables


Cables are the medium used to transfer data from one network device to another. Data must be sent from an origin to a destination, which necessitates the use of a transmission medium. The information is usually in the form of a signal that must travel a long distance. As a result, the transmission medium can either be wired or wireless. The transmission travels along the wire from one piece of equipment to another in the first instance. However, electromagnetic waves are conveyed without the use of a physical conductor in wireless transmission.

Wires of various sorts are commonly used in local area networks. In certain cases, a network will only use one type of cable, but a range of wire types will be used in others. The type of cable used in a network is directly related to the protocol and size of the network. Understanding the qualities of various types of cables and how they interact with other parts of a network is critical for the building of a successful network. In some industries, the type of cable used in network infrastructure is one of the most important parts of networking.

Compared to copper and silver, gold is not a conductor (and it is also more expensive), but it does have one advantage: it resists oxidation considerably better than the other two conductors. As a result, gold is used to coat plate connectors, whose connections may deteriorate if the surface becomes oxidized.

In chips, gold wire is used to connect the interconnects between the chip container and the silicon. When bonding, gold is used because it resists oxidation. Copper can also be utilized; however, it must be done in an inert atmosphere such as nitrogen.


Aluminum does not conduct as well as copper for a given cable size; however, aluminum has a better weight-to-conductivity ratio, aluminum cable with the same conductivity as the copper wire would be physically thicker but lighter, and possibly lighter cheaper.


Tungsten is used when the wire needs to be resistant and not melt even when white-hot, such as in incandescent lamps.


Silver has better conductivity than copper, although it isn't often used due to its costly cost. However, it has a few niche applications where extremely low resistance is desired, including sensitive scientific instruments, cryogenics (where minimal heat is produced in wires), and electrical contacts in switches, where the softness of silver and relatively good conductivity of silver-oxide make it a good choice for metal-to-metal connections.
