The new Enameled Wire with copper-clad aluminum material as an inner conductor has the characteristics between copper and aluminum, which combines the excellent conductivity of copper with the lightweight of aluminum.
In recent years, enameled wire industry has played an increasingly important role in the development of the national economy. However, due to the continuous rise in the price of electrolytic copper, it has brought great impact on the production of copper wire raw materials and enameled wire suppliers. The use of enameled copper-clad aluminum wire has proved that it can replace pure copper enameled wire, thus providing great business opportunities and the broad market for the development of enameled wire industry in China.
Traditional pure copper enameled wire mostly uses pure copper as raw material, which is not only costly but also limited by the shortage of resources. Enamelled copper-clad aluminum wire can not only replace pure copper equivalent (or super-effective) in equivalent fields but also greatly reduce the manufacturing cost. The replacement of pure copper and import by this product will surely play a strong role in promoting the development of national economy, upgrading the technical level of related industries and fields and reducing the manufacturing cost.
Compared with pure copper enameled wire, enameled copper-clad aluminum wire has obvious advantages:
The wiring density of enameled copper-clad aluminum is 1/3 of that of pure copper wire with the same wire diameter, which is very effective for reducing the weight of cables and coils. In the field of audio coils, product performance is obviously improved.
2. Good DC Resistivity
The DC resistivity of enameled copper-clad aluminum wire is about 1.5 times that of pure copper wire dacron. When the resistance values are the same, the wire diameter is about 1.2 times that of pure copper, while the weight of enameled copper-clad aluminum wire is only 1/2 that of pure copper wire.
3. Good solderability
The enameled copper-clad aluminum wire has the same solderability as the pure copper wire because the surface of the enameled copper-clad aluminum wire is concentrically coated with a layer of pure copper, and does not need to be specially treated like the aluminum wire.
4. Bottom Cost
Compared with pure copper enameled wire, enameled copper-clad aluminum wire can reduce production cost by 30%~50% in some application fields.
