Copper enameled wire is a new type of magnet wire with copper material as the inner conductor. Its characteristics are between the electrical conductivity of copper and the lightweight performance of aluminum.

Features:

1. DC resistivity: The DC resistivity of copper wire is about 1.45 times that of copper wire; under the same resistance value, the weight of copper wire is about 1/2 of that of copper wire.

2. Good solderability: copper wire has the same solderability as pure copper wire because its surface is concentrically coated with a layer of pure copper, without special treatment like aluminum wire; Thick copper layer to ensure that the soldering performance of the product will not be affected when oil is scraped;

3. Light weight: The density of copper wire is 1/2.5 of that of pure copper wire, which is very effective in reducing the weight of the coil; replacing copper wire with copper wire can save at least 30% of the cost.

Scope of application:

1. High frequency transformer, ordinary transformer;

2. Inductance, electromagnetic coil;

3. Motors, including household motors, various micro motors and compressors and other motors with high environmental requirements;

4. Special electromagnetic drive is used for audio coil and optical drive;

5. Electromagnetic wire used to display deflection coil;

6. The magnet wire of the degaussing coil;

Note items:

Copper enameled wire is ok for signal transmission, but now it is used for power transmission, which is prone to problems, and the service life of its products will be greatly reduced. In fact, when using copper enameled wire, pay attention to the oxidation protection of the lower enameled wire cut surface to ensure the effective combination of copper and aluminum, which can be used for a long time.

In fact, copper, copper, paint and other industries cannot be used, but in fact many companies are using transformers as transformers, which is very worrying. When using copper wire, there are two points to worry about. Its resistivity is higher than that of copper with equal cross-section, and the problem of temperature rise; aluminum wire is easy to be oxidized, which will further increase the resistance of the wire and prevent oxidation.
