Speaker coated aluminum wire, also known as ECCA wire, is a wire material with a coating applied to the surface of the aluminum conductor.ECCA stands for "Enameled Copper Clad Aluminum", meaning coated copper-clad aluminum.

The manufacturing process for ECCA wire is similar to that of enameled copper wire, but in this process a copper-coated aluminum wire is used. This wire material combines the advantages of aluminum and copper.

The manufacturing process for ECCA wire involves applying a copper layer to the surface of the aluminum wire. First, the aluminum wire is cleaned and surface treated to ensure that the copper layer adheres firmly to the aluminum surface. Then, the copper layer is uniformly coated onto the aluminum wire through plating or other coating processes. The thickness of the coated copper layer can be adjusted to meet specific application requirements. Finally, the copper layer is dried and cured to form a strong coating.

ECCA wire combines the properties of aluminum and copper. Aluminum has a lower density and good electrical conductivity, making ECCA wire lighter than solid copper wire. However, pure aluminum has relatively low conductivity, which can be improved by coating the aluminum surface with a copper layer. Copper is an excellent conductive material with high electrical conductivity.


ECCA wire is mainly used for speaker coil manufacturing. The coil is an important part of the loudspeaker, through the current in the wire to generate a magnetic field, which drives the vibration of the loudspeaker and produces sound.ECCA wire in the speaker coil to provide good electrical conductivity and insulation properties, to ensure that the quality of the transmission of audio signals, and to withstand the high temperatures and mechanical stresses of the loudspeaker operation.

ECCA wire has several advantages and features. First, it has a low density, so it can achieve lightweight design in some applications. Second, ECCA wire provides good electrical conductivity to transmit high quality audio signals. In addition, aluminum's resistance to corrosion gives ECCA wire a high degree of durability, allowing it to be used in a variety of environmental conditions.

When selecting ECCA cables, specific application needs and performance requirements need to be considered. For example, audio transmission quality, frequency response, coil size and power requirements. In addition, attention should also be paid to factors such as ECCA wire specifications, insulation, heat resistance and reliability.

ECCA wire is commonly used in coil manufacturing for speakers and audio equipment. Due to its light weight and good electrical conductivity, ECCA wire provides high quality audio transmission and occupies less space in audio equipment. In addition, the relatively low cost of ECCA wire can be an economical alternative to copper wire, providing cost-effectiveness in some applications.

ECCA wire is a wire material with a copper layer coated on the surface of aluminum wire, and is widely used in the manufacture of coils for speakers and audio equipment. It offers lightweight, good electrical conductivity and insulation properties, as well as corrosion resistance for a variety of audio applications. Choosing the right ECCA wire can meet the requirements of a specific application and ensure the performance and reliability of your audio system.
