FAQs About Copper-Clad Aluminum Conductor

Find answers to the most common questions about our Copper Clad Aluminum (CCA) wire below. If you need more engineering support, feel free to contact us.

What are the main advantages of Copper Clad Aluminum (CCA) wire over pure copper wire?

The primary advantages of CCA wire are significant weight reduction and cost savings. CCA wire is approximately 73% lighter than solid copper wire of the same diameter, making it much easier to handle and install. Furthermore, it offers up to 70% material cost savings while still delivering excellent electrical conductivity for high-frequency applications.

How does the "Skin Effect" make CCA wire suitable for high-frequency transmission?

In high-frequency alternating current (AC) applications, such as CATV coaxial cables and RF shielding, electrons naturally migrate toward the outer surface of the conductor—a phenomenon known as the "Skin Effect." Because FISSOT®'s CCA wire has a high-purity copper outer layer, high-frequency signals travel almost entirely through the copper, resulting in performance identical to pure copper conductors but at a fraction of the weight.

Can you solder copper clad aluminum wire?

Yes. The seamless copper cladding on our CCA wire ensures that its surface characteristics are identical to those of pure copper. It offers excellent solderability, corrosion resistance, and can be easily processed using traditional bunching, stranding, and enameling techniques without the need for special aluminum fluxes.

Is copper clad aluminum wire good for automotive use?

Yes, FISSOT® CCA wire is highly beneficial for automotive wire harness lightweighting. It delivers a substantial weight drop (up to 40% reduction vs. pure copper) which enhances vehicle fuel efficiency and battery range in electric vehicles, while perfectly meeting the mechanical requirements for low-voltage signal transmission and automotive sensor wiring.

In which industries is 10% vs. 15% volume CCA wire typically used?

Our 10% copper volume CCA wire (typically offering 63% IACS) is the standard choice for CATV coaxial cables, audio cables, and light-duty power cables where weight and cost are primary concerns. The 15% copper volume variant provides slightly higher conductivity and enhanced surface durability, making it ideal for more demanding applications like magnet wire windings, automotive harnesses, and high-grade RF shielding.
