The electric potential of enameled copper wire and enameled aluminum wire is different. Due to the reaction of the primary battery, the contact part of the enameled copper wire and the enameled aluminum wire will accelerate the oxidation of the aluminum wire. After a long time, the enameled copper wire and enameled aluminum wire connectors are in poor contact. If you want to connect them together, you must use enameled copper wire and enameled aluminum wire to wrap or wrap the pipe.
The chemical properties of metals are relatively active and inactive. For example, gold never rusts. This means that gold is chemically inert, iron is prone to rust, and iron is more active than gold. Putting the metals together will accelerate the oxidation of the active metals. Compared with Round Enameled Copper Wire, enameled aluminum wire is more active. The connection of the two cables will accelerate the oxidation of aluminum (that is, rust) and affect the use.
