Common Electrical Wire Material Options

Day to day living largely depends on electricity in the modern world. Electricity has so many applications that without it would be hard to get anything done. Electrical wires are what are used to carry the much needed energy into places of work, homes and even in automobiles and other different equipment and appliances. For this reason, the wires used in the different electrical applications need to be in optimal condition if at all they are to get things running as smoothly as they should.

With so many  options available in the market, it is wise to always weigh your options and the exact wire features your kind of application require so you are able to select the most suitable one at the end of the day. It is the best way of ensuring safety when using electricity and wire materials are some of the most important to consider for any given application. What your wire is made up of determines its quality and suitability for the intended use.


It is considered standard in the wiring area with most electrical appliances relying on copper wires to transfer energy. One of the major reasons why copper is a great material is its high conductivity and flexibility. Compared to other metals, copper seems to win also in resistance to corrosion, tensile strength, ductility, thermal conductivity and also resistance to overloads. Because of the abundance of copper, the battery cable made of copper are reasonably priced.


It may be more abundant and cheaper compared to copper, but it is not as conductive as copper. You would need a relatively larger aluminum wire in diameter to have it functioning the same way as a copper wire. Aluminum is also not as reliable in terms of electrical safety because it can't withstand excess heat. When going for this kind of electrical wire, especially for commercial purposes, it is best that you settle only for larger diameters.


It is a good conductor of electricity and is most suitable in high temperature conditions. Silver wires are however not that easy to bend and they can also be very expensive. In commercial applications, electrical safety would actually be compromised unless silver electrical wires are used. Most people prefer using these wires at home for their entertainment equipment because signals seem to travel far much better through pure silver compared to copper.

When looking for the best electrical wire for your application, it is only important to consider the material that makes up the wire, but also the type of wire you are going for. The wire gauge size and the manufacturing of the  can also help you in choosing the most suitable wire for the exact electrical needs you have. Most electrical wires come insulated with materials such as Teflon or silicone. You can also take those into consideration because they come with different properties that can help you make the right decision depending on what you are looking for in a wire.

Quality is the one thing that matters most whether you are looking for silicone wire, high temperature wire or even hook up wire. Find a trustworthy and reputable supplier for your electrical cables and wires to enjoy superior quality.

  • Interesting comparison. I see aluminum used a lot in aerial service entrances. Since it is not in conduit, its larger diameter is not an issue. Also, since it is exposed to the air, overheating is less likely as well.
  • In reply to Leonardo David:

    The only time I have seen aluminum wires is for service feeds where larger cable is more price friendly in aluminum.  There is however, a lot more preparation required like using Penetrox on the stripped wire end before terminating to help against oxidation. Also coming back to re-torque connections is required because aluminum wires expand and contract with temperature change and can get flattened out over time creating loose connections making hot spots.

    When working with smaller gauge copper wire do you prefer using stranded or solid wires?

  • In reply to Moe Khajavi:

    Stranded, due to its flexibility. It's much easier to pull through conduit, especially when there are turns.
  • Thanks for sharing good information.
