Which is better copper or aluminum wire?
Copper wiring is more stable than aluminum and smaller conductors are needed to transmit power loads. Overall all it is more durable and performs better than aluminum wiring. … Aluminum is much lighter and malleable than copper and therefore, makes it easier to work with.
How long does aluminum wire last?
For example: The copper inside the wires can last over 100 years. The aluminum inside the wires can last between 80 and 100 years.
Is aluminum wire still used?
Utility companies have used aluminum wire for electrical transmission in power grids since around the late 1800s to the early 1900s. It has cost and weight advantages over copper wires. Aluminum wire in power transmission and distribution applications is still the preferred material today.

Aluminum wiring is safe if properly installed. Use only CO/ALR wall switches and outlets. If your home has aluminum wiring and you need to replace a switch or outlet, the replacement should be a type that is specifically approved for use with aluminum wiring. Approved devices are marking “CO/ALR”.
What is the disadvantage of using aluminum wire?
Disadvantages of aluminum wiring: Aluminum conductors are going to be larger than that of a comparable copper conductor. … Aluminum wiring raises potential risk for house fires if not installed with great care and diligence. Expansion and contraction cycles in aluminum have greater impact compared to use of copper.
Is Pigtailing aluminum wiring safe?
Pigtailing aluminum wiring is safe as long as proper terminals and connections are made – without damaging the wire – and with materials approved by the Canadian Electrical Code. Aluminum wiring pigtails approved by the Electrical Safety Authority are the most common solution for making aluminum wiring safe.
