Is aluminum wiring a deal breaker?
“Problem is, aluminum expands and contracts in the heat more than copper, which causes the connections to loosen up, and then you get fires.” If the house does have aluminum wiring, an electrician can add copper near the outlets—but that’s akin to putting a Band-Aid on a bullet wound.
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.
Can you rewire a house without removing drywall?

At the time, aluminum was a cheaper substitute for 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.

Why did they stop using aluminum wiring in homes?
Softness: Aluminum is a much softer metal than copper. Electricians who had always worked with copper found that it was very easy to nick, cut, or crush the aluminum wiring when removing insulation or making connections. They had to be gentler. Damaged wire creates local hot spots and results in overheating.
Is it OK to mix copper and aluminum wiring?

How do you make aluminum wiring safe?
But an electrician can make the connections safe by adding a short section of copper wire to the end of each aluminum wire. That way, copper rather than aluminum will be connected to each switch, outlet or other device.
What happens when you mix aluminum and copper?
Mixing copper and nickel in a liquid cooling loop with aluminum parts will induce galvanic corrosion and the more active aluminum will get damaged. This can also lead to the damage to the nickel plating since it is a thin coating. Corrosion happens regardless in all systems whether they have mixed metals or not.
What happens when aluminum and copper touch?
A. Aluminum will be very susceptible to galvanic corrosion in contact with copper, assuming that the two metals are also in contact with a common electrolyte (such as water with some ionic content.) … This will improve bolted joints by reducing the resistance, and resists corrosion.
Should you replace aluminum wiring?
