Copper vs. Aluminum Wiring: Which Is Better?

Copper and aluminum are the two most prevalent materials in wiring. Advantages and disadvantages exist for both, so let us present the unbiased case of which wiring is better between copper and aluminum, letting you make the best decision.

The Case for Aluminum

The opening argument aluminum would make to plead its case in an open court would be its affordability. Aluminum wiring for a home or commercial building can be kinder to your budget, considering it’s half the price of copper wiring. Aluminum is also much lighter than copper, making it easier to work with in certain situations and ideal for longer distances.

You won’t find a more resistant material than aluminum, which is clear when working with power cables. Along with being half the price of copper, aluminum requires about half of the cross-sectional area of copper conductors to convey the same current.

The Benefits of Copper

While aluminum can tout itself as the cost-effective and lighter option, copper would plant its flag as the more durable and conductive material. Many builders prefer copper when the price isn’t a concern because of its long-lasting properties.

The robustness of copper wires makes them less prone to break than their aluminum counterpart. When you are tugging on a wire to pull it through feeders and ports, it’s nice to have the assurance that it remains intact. Copper wire has less thermal expansion than other materials, so excess heat doesn’t cause it to expand.

Aluminum’s Faults

Although aluminum may be the less costly option between the two, there is a good reason for that. Aluminum is nowhere near as strong as copper. The difference in strength is why aluminum is so inexpensive in comparison. An additional downside of aluminum is its vulnerability to corrosion. You know copper is in it for the long haul, but you’ll always be concerned about aluminum wiring.

Copper’s Flaws

The primary negative of using copper boils down to its cost. Unfortunately, some folks don’t have an endless supply of money. They cannot write a blank check to a contractor and tell them to fill it out. Copper wiring is a hefty investment that isn’t in the cards for everyone. On the bright side, you get what you pay for: dependable wiring.

The weight of copper wiring may throw a wrench into construction plans because the extra weight requires more structural support. This consideration will also put a dent in your budget.

Deciding which is better between copper and aluminum isn’t always cut and dry. On the one hand, you save money when you use aluminum, but you’re using a weaker material. You could also use the best long-term solution and take the upfront financial hit.
