The enameled aluminum strip is a new type of enameled wire that uses copper-clad aluminum as the inner conductor. Its characteristics are between copper and aluminum, and it combines the light weight of aluminum and the excellent conductivity of copper. Therefore, the current application continues to expand. Specifically, aluminum enameled wire has obvious advantages compared with pure copper enameled wire:
- More excellent DC resistivity, the DC resistivity of aluminum enameled wire is approximately 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, while the weight of aluminum enameled wire is only pure copper wire 1/2.
- Lighter weight. The density of aluminum enameled wire is one third of that of pure copper wire with the same wire diameter. It is very effective in reducing the weight of cables and coils. In the field of audio coils, it greatly improves product performance.
- Lower cost. Compared with pure copper enameled wire, aluminum enameled wire can reduce the production cost by 30%-50% in some application fields.
- The solderability is better. Aluminum enameled wire has the same solderability as pure copper wire because its surface is coated with a layer of pure copper concentrically, without special treatment like aluminum wire.
The above are some of the advantages of enameled copper square wire.
