Aluminum Wiring Versus Copper

By | July 25, 2022



Today, when it comes to wiring for home electrics, many people are torn between using aluminum wiring versus copper. Both have advantages and disadvantages dependant on the particular environment, so it is important to understand the subtle differences between the two before deciding which is best for your needs.

Aluminum wiring has been used as an electrical conductor since the early 1900s and was popular in the 1960s and 70s, primarily used due to its cost effectiveness. Today, aluminum is still the go-to option for certain jobs- typically for large projects such as a grid-tied solar system that requires long wiring runs. Aluminum is significantly more lightweight than copper, which makes it a practical choice for large scale projects. Furthermore, it is relatively inexpensive in comparison with other wiring materials.

On the other hand, copper wiring has become increasingly popular over the years. In most cases, it is an excellent choice for wiring home electrics, as it is considered to be more reliable and durable than aluminum. Despite its high cost, it is often worth the investment as it offers superior conductivity, making it more efficient than aluminum. Additionally, it is incredibly flexible and easy to work with.

Ultimately, whether to use aluminum wiring versus copper is largely dependant on personal preference and the requirements of the individual project. For large scale installing where weight and cost are important considerations, aluminum might be a good option. However, where reliability and efficiency are top priorities, copper is usually the material of choice.
