Is there such a thing? old wiring is usually copper and the scrap value is quite high.
Today the only use of aluminum wire is in service entrances and underground feeds where the larger sizes are needed. By using aluminum the overall project wire costs are kept to a minimum even with the bigger size needed over copper. Wiring branch circuit in aluminum has not been vogue for many years now.
depending on the age of the house, wiring could be several types. Wire known as romex has been used for several years. In very old homes wiring could be two separate wires using glass insulators to separate them.
If there is not enough slack to create a pigtail connection, you can use a junction box to extend the old wiring. Cut the old wire short, strip the insulation, and connect it to a new wire with a wire nut inside the junction box. Make sure to secure the junction box properly and follow all local electrical codes.
aluminum wire expands and contracts with heat. copper is more stable. unfortunately you have aluminum. in a device connection, its not an issue. just make sure that your connection is secure, by pulling on the individual wires of the connection to be sure the wire doesn't pull apart. what you should check is the screws that hold your aluminum wire at the source, make sure those connections are tight. a loose connection will generate excessive heat.heat will melt metal, plastic, and cook body parts.make sure you are not grounded when you touch the source. I know of no electrician who would use aluminum wire in any application except a service entrance. I used copper on my own houses. Yes. You need special Al or AlCu devices for aluminum. Remeber aluminum reacts with copper so you can't connect aluminum to copper. Idontreallycare - Aluminum wiring was used in houses built in the 60s when there was a shortage of copper due to the Vietnam war. It is no longer used in new construction, but still exists in old houses
Answer for USA, Canada and countries using similar 60Hz household electrical servicesBlack insulated wire is used for a "Hot" (or "Live") wire. Answer for European and other countries using similar 50Hz household electrical services In old wiring, as was used for household electrical circuits installed in the UK prior to 2006, the "Neutral" would have been a black insulated wire. Black insulated wiring is not used for that purpose today. For more information see the answers to the Related Questions shown below.

You can find copper in household wiring, plumbing pipes, pots and pans, electronics, and decorative items such as faucets and light fixtures.
To identify old house wiring for safety and maintenance purposes, you can hire a professional electrician to conduct an inspection. They can check for outdated wiring materials, such as knob-and-tube or aluminum wiring, and assess the overall condition of the wiring system. Additionally, look for signs of wear and tear, such as frayed insulation or exposed wires, and consider upgrading to modern wiring standards for improved safety and efficiency.

To properly install and troubleshoot household switch wiring, follow these steps: Turn off the power to the circuit at the breaker box. Remove the old switch and disconnect the wires. Connect the new switch by matching the wires to the corresponding terminals. Secure the switch in place and turn the power back on. Test the switch to ensure it is working properly. If the switch is not working, check for loose connections or faulty wiring. Remember to always follow safety precautions when working with electricity. If you are unsure, consult a professional electrician.
