OFC vs CCA cables – Oxygen Free Copper vs. Copper Clad Aluminum Cables

The speaker cords in your audio system are essential. They let you to run a single wire from the power socket to your speakers, carrying signals and power from one device to the next. They are available in a variety of functions and configurations, some with coaxial shielding and others without.

The two most popular high-current speaker wires for vehicle amplifier wiring are copper-clad aluminum and oxygen-free copper (Ofc) (Cca). The decision depends on your selected characteristics, despite the fact that these two types of power cable have significant distinctions.

What is Oxygen Free Copper (OFC) Cable?

An electrical cable known as an OFC wire is made out of an insulated copper wire that has been wrapped in a fiberglass or plastic jacket. This top layer shields the copper from corrosion, which could short circuit electrical systems and shorten their lifespan. Because they are simple to install and have good electrical conductivity, OFC cables are frequently utilized in automotive audio wiring.

The unified numbering system (UNS), which specifies the amount of oxygen in copper composition, is used to create numerous standards that are part of the OFC. 0.0005% of oxygen is present in oxygen-free electronic (OFE), compared to 0.001% in oxygen-free (OF). Additionally, the electrolytic tough pitch (ETP) has an oxygen concentration that ranges from 0.02% to 0.04%.

For high-frequency applications, such as telephone or computer lines, all three standards are employed since they transmit electricity with less resistance.

What is Copper Clad Aluminum (CCA) Cable?

Copper-clad aluminum power wire might be an excellent choice if you want to enhance your amplification equipment. Its wire is created by enclosing an aluminum inner core in a copper outer layer. The outer layer serves as a handy location to attach connectors and shields the inner core from physical harm.

Copper-clad aluminum wire’s simplicity and affordability are by far its greatest advantages. If you’re searching for something that fits within your budget or time limits, this wire is a wonderful option. Electrical cabling systems, such as data and power cables, use CCA wire because it conducts electricity far more effectively than pure copper.

CCA vs OFC – Which is better?

Due to the skin effect, copper-clad aluminum wires have a higher resistance when they are warmer than when they are cooler. As a result, they are less effective at transmitting electricity than copper wires without oxygen since it requires more energy to conduct electricity through them.

Cheaper than oxygen-free copper wire is copper-clad aluminum wire. This is so because oxygen-free copper costs more to produce and costs more to install. In comparison, copper-clad aluminum is easier to install and has reduced manufacturing costs. However, over time, ofc is more cost-effective because repair and maintenance expenses are reduced to a minimum. Consider your options before committing fully to CCA wiring.

Copper-clad aluminum wires are less resilient to vibration and impact than OFC copper wires. This explains why they are frequently employed in industrial or building operations that involve such forces.

That concludes our thorough comparison of CCA vs. OFC speaker cables. As you can see, OFC wires win the day because to their excellent features. In conclusion, the OFC wiring kit is the best option if you want a wire that will provide durability, effectiveness, and high conductivity.

But if weight and price are your major concerns, go for CCA wire instead of pure copper wire, which is more affordable. Use a bigger gauge wire size while working with CCA for the best outcomes and durability. Your preference is entirely up to you to decide.
