Enameled Round Aluminum Wire

Enamelled round aluminum wire is a widely used conductor material in electrical and electronic devices, particularly in the manufacturing of coils for motors, transformers, generators, refrigeration systems, heat-resistant motors, and other electrical equipment.

The core material of enamelled round aluminum wire is aluminum, which has good conductivity and lightweight properties. Compared to copper wire, aluminum wire has a lower density and is more cost-effective, making it a substitute for copper wire in many applications.

Although aluminum's conductivity is not as high as that of copper, its lightweight and cost advantages make it the preferred choice in many applications. The resistance of enamelled round aluminum wire is relatively low, ensuring minimal energy loss during current transmission.
