The Enameled Copper Clad Aluminum Wire uses copper clad aluminum material as the inner conductor, which is a new type of electromagnetic wire. It combines the excellent conductivity of copper with the light weight of aluminum, and its characteristics are between copper and aluminum. Enamelled copper clad aluminum wire is widely used in transformers, inductive electromagnetic coils, acoustic coils, electromagnetic wires for demagnetization coils, etc. It has high DC resistivity, light weight and good solderability. But at the same time, there are also several aspects that need attention.

Due to low cost, most enterprises use copper clad aluminum wire in power transmission and transformer, and enameled copper clad aluminum wire cannot be used in many fields. The resistivity of copper clad aluminum wire is higher than that of copper wire, and the problem of temperature rise is worthy of attention. In addition, aluminum wire is easy to oxidize, which will further increase the resistance. Measures to prevent oxidation should be taken during use to avoid losses. The enameled copper clad aluminum wire can be used for signal transmission, but it will cause great problems in power transmission and reduce the service life of its products. When in use, attention should be paid to protecting the section of enameled wire to prevent aluminum oxidation and ensure the effective combination of aluminum and copper, which can also prolong the service life. What needs most attention is that there is no real demonstration in the industry as to whether the copper aluminum bonding ability can stand the test during the long-term use of this new type of metallurgical bonding electromagnetic wire and the process of expansion with heat and contraction with cold.

However, enameled copper clad aluminum wire still has many advantages such as low cost, lightweight and excellent conductivity. Reasonable use and protection can prolong the service life and greatly reduce the cost.
