Pure Copper vs Copper Clad Data Cable: What You Need to Know

19 Oct 2023
When setting up a network infrastructure, choosing the right data cable type is crucial for ensuring optimum performance and reliability. Two popular options are pure copper cables and copper-clad aluminum (CCA) cables. Each has advantages and drawbacks, and your choice can significantly impact your network's speed, functionality, and overall cost. In this blog post, we delve into the differences between pure copper and copper-clad data cables to help you make an informed decision.

What are Pure Copper and Copper Clad Cables?


Pure Copper Cables


As the name suggests, pure copper cables are made entirely of copper. Known for its excellent electrical conductivity, pure copper is often the preferred choice for high-performance networks.

Copper-Clad Aluminum (CCA) Cables


CCA cables feature an aluminum core coated with a copper layer. This design aims to offer a compromise between copper's conductivity and aluminum's lightweight and cost-effectiveness.

Conductivity and Signal Strength


Pure Copper


Copper is known for its superior electrical conductivity. This reduces signal loss, making pure copper cables ideal for high-speed data transmission over longer distances.

Copper-Clad Aluminum


CCA cables don't offer the same level of conductivity as pure copper cables. The presence of aluminum means that these cables can experience higher signal loss, especially over extended distances.

Weight and Flexibility


Pure Copper


Being entirely made of copper, these cables are generally heavier and less flexible. While this isn't usually a problem in stationary installations, it might be a consideration for applications where the line needs to be moved frequently.

Copper-Clad Aluminum


CCA cables are lighter and more flexible due to their aluminum core. This makes installing them easier in tight spaces or areas where the cabling will be frequently rearranged.

Durability and Lifespan


Pure Copper


Pure copper cables are incredibly durable and can withstand various environmental conditions. They are less likely to break or deteriorate over time, making them a long-lasting option.

Copper-Clad Aluminum


The aluminum core in CCA cables is more prone to oxidation and is generally less durable than pure copper. This can result in a shorter lifespan and may require more frequent replacements.

Cost


Pure Copper


The primary downside of pure copper cables is their cost. Copper is a more expensive material, which can quickly add up for extensive networking projects.

Copper-Clad Aluminum


CCA cables are generally less expensive due to the aluminum core. For budget-conscious projects, they might seem like an attractive option.

Compliance and Standards


Pure Copper


Pure copper cables usually meet higher industry standards, including those set by organizations like the Telecommunications Industry Association (TIA) and the International Organization for Standardization (ISO).

Copper-Clad Aluminum


CCA cables may not meet some industry standards, particularly for specific high-performance applications. Always check the cable's compliance with your specific project's requirements.

Applications: Where Each Type Shines


Pure Copper



  • High-speed networks

  • Long-distance data transmission

  • Industrial applications

  • High-quality audio and video transmission


Copper-Clad Aluminum



  • Short-distance runs

  • Residential networking

  • Light-duty applications


Choosing between pure copper and copper-clad aluminum cables depends on factors like required conductivity, flexibility, durability, cost, and compliance with industry standards. Pure copper cables are ideal for high-performance, long-lasting installations, while copper-clad lines may be suitable for shorter runs and budget-friendly projects.

Before making a decision, consider your specific needs and consult with a professional to ensure you're choosing the right cable type for your application.

Why Your Company Should Avoid CCA Cabling – Part 2

30 Oct 2018

Cat6 Office Cabling Dallas TX Pittsburgh PAAs discussed in Part 1, companies that have a limited budget for network infrastructure may end up buying copper clad aluminum (CCA) cabling to save money. Although marketed as a sufficient substitute for solid copper cabling, CCA cables are far from being the right answer for trimming budgets. Part 2 will continue discussing CCA cabling related issues and counterfeit copper cabling.



Shortened Cable Runs


As lengthier CCA cable runs approach the 100-meter maximum, there will be a decrease of signal strength in comparison to solid copper CAT5e cabling. Reduced signal strength can result in data loss because increased packets of data must be retransmitted.


Unsuitable for Power Over Ethernet (PoE)


Since CCA wires have a higher DC resistance (about 55% greater) than solid copper, its conductors may need to be 60% larger than solid copper to compensate. Without resistance compensation, the drop in voltage will be greater for any channel length.


Longer cable runs of 65 meters or more will surpass TIA’s channel DCR requirements, limiting the available voltage for the device. In addition, higher resistance will result in a faster buildup of radiant heat, which may damage the device.



How to Identify CCA Cabling


CCA wire is also much more brittle than solid copper wire. Identifying CCA is easy because all you need to find is the silver color of the tip of the conductor. Another way is scraping away the thin copper surface of the conductor to reveal the aluminum.


CCA cables also weigh much less than solid copper cables. Go to the CCCA website for the CableCheck™ mobile app (http://cccassoc.org/news/free-apps/), which provides the approximate correct box weights to help detect CCA conductors being used to fraudulently substitute for solid copper conductors.


When a CCA cable is labeled as a Category 5e, 6 or 6A cable or CMP or CMR rated, it is counterfeit cable. It will also be non-compliant with industry performance standards and will pose a hazard by being unable to pass UL fire safety testing.
