Copper clad aluminum, CCA wire, CCA

Copper clad aluminum wire is a composite wire consisting of an aluminum core clad with copper stripThe material is 85% aluminumThe wire has high frequency electrical properties equal to solid copper Wire, Copper clad aluminum wire, bare, plated, and film insulatedCopper clad aluminum is widely used in applications requiring the conductivity of copper while retaining much of the weight advantages of aluminumBy fine wire drawing machine, it can be drawn even up to diameter of 0.01mm and our current diameter size available is: 0.10-2.00mm.

Application

The primary applications involve of this conductor revolve around weight reduction requirements. These applications include high-quality coils, such as the voice coils in headphones, portable loudspeakers or mobile coils; high frequency coaxial applications; such sa RF antennas; CATV distribution cables; and power cables.CCA was also used in mains cable for domestic and commercial premises. The copper/aluminium construction was adopted to avoid some of the problems with aluminium wire, yet retain some of the cost advantage. But, solid copper is most commonly used in internal residential 120v or 240v wiring in the USCCA became extremely popular on emerging markets as a cheap replacement for copper category 5e twisted pair cables.

Skin Effect

The skin effect causes alternating current to concentrate on the more-conductive copper cladding of the conductor, causing the resis tance of the wire to approach that of a pure copper wire at high frequencies, which makes the copper-clad aluminum wire a good fit for such applications. The skin effect is also utilized in copper-clad steel wire such as RG-6 coax, which is also commonly used in high frequency with high strength requirements.
