Copper and aluminum enameled wire

 Combination of copper and aluminum . Copper and aluminum enameled wire is actually an enameled wire made of copper and aluminum. The earlier enameled wire is actually oily enameled wire, which is made of tung oil. The paint film has poor abrasion resistance and cannot Polyamide Imide Composite Aluminum Wire be directly used to manufacture motor coils and windings. It needs to be covered with cotton yarn when it is used. Later, polyvinyl formal enameled wire came out, one of its mechanical properties was greatly improved, it can be directly used in motor windings, and we call it high-strength enameled wire. With the development of weak current technology, there has been a self-adhesive enameled wire, which can obtain a coil with better integrity without dipping and baking. But its mechanical strength is poor, and it can only be used in micro motors and small motors.
