CCA wire is an electrical conductor composed of an inner aluminum core and an outer copper clad layer.

CCA wire is an electrical conductor composed of an inner aluminum core and an outer copper clad layer. The main application of this conductor revolves around weight reduction requirements. These applications include high-quality coils, such as voice coils in headphones or portable amplifiers; high-frequency coaxial applications, such as RF antennas and cable television distribution cables; and power lines.

 CCA wire has a very thin copper-coated aluminum wire. At first glance, it looks the same as pure copper wire. The price may seem attractive, but remember that the conductivity of aluminum is only 60% of copper. This means that to withstand the same load, you must use a thicker wire gauge, which can save a lot of costs. Replacing copper wires of the same specifications with CCA wires is dangerous and may cause the wires to burn or catch fire. In addition, it is not as flexible as copper, so it is more difficult to process, and single strands may break when bent excessively. It is also more prone to corrosion.

Like aluminium Magnet wire, CCA is also used for electrical wiring in buildings. The described copper/aluminum structure is obtained by avoiding some problems with aluminum wires, but still retains most of the cost advantages.
