When it comes to electrical wiring, most people probably don’t think about what the wires are actually made of. Typically, they are made out of highly conductive metals that are efficient at carrying electric currents, but did you know that the type of metal most commonly used has changed? Older houses were often wired with aluminum wiring. If you think of aluminum foil used for cooking, you’ll probably realize how conductive it is, but it’s unlikely that you’d use that foil over and over again. That is why most modern houses use copper wiring since it’s more durable and effective over long periods of time. It’s also much cheaper, so if your house uses aluminum wiring, consider contacting a professional for electrical repairs that replace your aluminum wiring with copper wires.
