1.Lighter than pure copper 2.Higher conductivity than pure aluminum 3.Higher strength than aluminum
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 as 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 US.
CCA became extremely popular on emerging markets as a cheap replacement for copper category 5e twisted pair cables.
