A new type of enameled wire using copper-clad aluminum material as the inner conductor, its characteristics are between copper and aluminum, combining the excellent conductivity of copper and the advantages of light weight of aluminum.
In recent years, the important position and role of the enameled wire industry in the development of the national economy has become more and more prominent, and due to the continuous rise in the price of electrolytic copper, it has brought a huge impact on the production of related copper wire raw materials and enameled wire suppliers. Copper clad aluminum enamelled
The wire has been proved by users to replace pure copper enameled wire, thus providing a huge business opportunity and a broad market for the development of my country's enameled wire industry.
Traditional pure copper enameled wire mostly uses pure copper as raw material, which is not only costly, but also limited by resource shortage. The copper-clad aluminum enameled wire launched by our company can not only replace pure copper equivalently (or super-effectively) in a certain field, but also greatly reduce the manufacturing cost. The improvement of the technical level and the reduction of manufacturing costs in related industries and fields play a strong role in promoting.
Compared with pure copper enameled wire, copper clad aluminum enameled wire has obvious advantages:
1. Light weight
The density of copper-clad aluminum wire is 1/3 of that of pure copper wire with the same wire diameter, which is very effective in reducing the weight of cables and coils. In the field of audio coils, it can significantly improve product performance.
2. Good DC resistivity
The DC resistivity of copper-clad aluminum wire is about 1.5 times that of pure copper wire; when the resistance value is the same, its wire diameter is about 1.2 times that of pure copper, and the weight of copper-clad aluminum wire is only 1/2 of pure copper wire.
3. Good solderability
Because the copper-clad aluminum wire is concentrically coated with a layer of pure copper, it has the same brazability as pure copper wire, and does not need special treatment like aluminum wire.
4. Low cost
Compared with pure copper enameled wire, copper-clad aluminum wire can reduce production cost by 30%-50% in some application fields.


Copper clad aluminum enameled wire application range:
1. It is used to make windings that require light weight, high relative conductivity, and good heat dissipation, especially windings that transmit high-frequency signals.
2. Enameled wires for high-frequency transformers, ordinary transformers, inductance coils, motors, household motors and micro motors.
3. Enameled wires for rotor coils of micro motors.
4. Special electromagnetic wires for audio coils and optical drives.
5. Magnet wire for display deflection coil.
6. Electromagnetic wire for degaussing coil.
7. Electromagnetic wires used for internal coils of mobile phones, driving components of watches, etc.
8. Other special electromagnetic wires.
