Product Description

0.035mm CCA Wire Self Bonding Magnet Wire Voice Coil Wire




CCA is an electrical conductor composed of an inner aluminium core and outer copper cladding,The primary applications of this conductor revolve around weight reduction requirements. These applications include high-quality coils, such as the voice coils in headphones or portable loudspeakers; high frequency coaxial applications, such as RF antennas and cable television distribution cables; and power cables.



Light weight. Only 50% of copper at the same length


Good ductility and bending strength

High fidelity sound quality



Micro voice coil speakers



HIFI stereos
