Copper clad aluminum wire, commonly abbreviated as CCA, is composed
of a thin layer of copper over an aluminum core with the copper
making up ten percent of the wire’s volume. Copper clad aluminum is
particularly useful in high-quality coils where weight matters like
in mobile coils. For example, voice coils in headphones and
portable loudspeakers should be light.
Copper clad aluminum wire is also used in overhead coaxial cable
for high frequency television signals. It replaces copper as a
grounding conductor on structures. Some of the benefits of copper
clad aluminum wire are:
1. Copper clad aluminum (CCA) wire is less expensive than copper
2. CCA wire is lighter than copper wire.
3. CCA wire has higher conductivity than aluminum wire.
4. CCA wire has higher tensile strength than aluminum wire.
5. CCA wire offers better solderability than aluminum wire.
6. CCA wire offers equal corrosion resistance to copper wire.
7. CCA wire offers equal signal frequency to copper wire.
8. CCA wire is easier to install than copper wire.
9. CCA wire is more flexible than copper wire.

Copper clad aluminum wire is especially suitable for high frequency
applications. Even though it is comprised of 90% aluminum, its high
frequency electrical properties are equal to solid copper.

The strong economic advantage that copper clad aluminum has over
pure copper makes it a logical choice to replace the more than 45
pounds of copper wire that are found in a typical automobile's
