Standard Romex is a three-strand, solid core wire, individually insulated, in a common sheath to make it easier to pull. For a short time, some manufacturers were making romex with aluminum because the cost of copper was so high, but the aluminum wire was not as good as the copper, and the practice was discontinued.
No, do not mix aluminum wire with copper wire.
The standard Romex wire colors used in electrical wiring are black, white, and bare copper.
Copper wire gauge sizes are not equivalent to aluminum wire gauge sizes. The gauge sizes for copper and aluminum wires are different due to their differing electrical conductivity properties. It is not possible to directly convert a copper wire size to an equivalent aluminum wire size.
Copper wire connectors are more conductive and resistant to corrosion compared to aluminum wire connectors. However, aluminum wire connectors are lighter and less expensive than copper wire connectors.
To effectively connect aluminum to copper wire using an aluminum to copper wire connector, follow these steps: Strip the insulation off the ends of both the aluminum and copper wires. Insert the stripped ends of the wires into the aluminum to copper wire connector. Use a crimping tool to securely crimp the connector onto the wires. Ensure the connection is tight and secure before using the wires for electrical purposes.
Copper wire has greater resistance than aluminum wire. This is because copper is a better conductor of electricity than aluminum. This means that copper wire will have less resistance and will be able to carry more current with less energy loss.
In the electrical trade aluminum wire is equivalent to copper wire as it is also used to carry current. To carry the same current as copper wire aluminum wire is up sized to meet the same ampacity.
No, copper and aluminum wire of the same length and diameter will not have the same resistance. Copper has a lower resistivity than aluminum, so a copper wire will have lower resistance compared to an aluminum wire of the same length and diameter.
When compared by volume, copper is best, then aluminum and finally iron. When compared by weight, aluminum is better than copper. You have to compare by volume because aluminum is so much lighter than copper, an aluminum wire that weighed the same as a copper wire would be much bigger and harder to work with.

The best practices for safely connecting aluminum to copper wire using aluminum to copper wire nuts include ensuring the wires are clean and free of corrosion, using antioxidant compound, twisting the wires together tightly, and securely fastening the wire nut. It is also important to follow manufacturer instructions and consider consulting a professional electrician for guidance.
