Advantages of CCA:1. Light-weight: CCA is about one-third of the weight of copper wire of the same thickness. This is extremely advantageous for reducing the weight of the coil2. DC resistance: CCAW has about 1.5 times the DC resistance of copper wire. Because it is three times as light as copper wire, however, only one-half of the weight of copper wire is needed to handle the same current3. Soldering: Because the surface of the conductor of CCAW is clad with copper, there is no need for special soldering as is the case with aluminum wire. Soldering can be done in exactly the same way as with copper wire.
