Copper Clad: Everything You Should Know

Do you want to learn more about Copper clad and all the things you can make with it? Then, this article is the perfect place to get started.

For years, Copper clad has been the go-to for many wiring applications because of its high conductivity and low resistance.

Unfortunately, understanding and choosing the perfect Copper plating products, especially with heavy copper PCB for your projects, could be pretty tricky.

But thankfully, we created this article to give you an in-depth look into everything you need to know about these heavy copper metals and how to choose the perfect annealed Copper for your project.

1. What is Copper Clad Made Of?

Copper clad is composed of two metals.

How?

To create a copper-clad, a second metal (core material) must be enveloped within the copper plating. Additionally, while they are not 100% copper, they maintain similar attributes and capabilities to Copper.

Thus, copper-clad materials can comprise:

• Copper and steel
• Copper and aluminium
• Copper with various reinforcing materials

2. What Are the Advantages of Copper Clad Products?

Various copper plating products come with distinct benefits.

Here are some advantages of these products:

Copper Clad Aluminium Wire (CCA or CCAW)

The Copper coat aluminium wire consists of an aluminium core encased in Copper for enhanced electrical conductivity.

Thus, CCA can be utilized for electrical wiring, power cables, and voice coils found in earphones.

Advantages

Compared to copper wires, CCA wires are more cost-effective and exhibit high resistance akin to pure copper conductors due to the skin effect. This skin effect allows the wire to center currents on its copper surface, making it suitable for frequency applications and coaxial cables.

Moreover, CCA is lightweight and retains remarkable properties of pure copper wire while mitigating the disadvantages of pure aluminium.

Copper Clads Steel (CCS)

Copper clad steel entails steel coated in Copper. This electrical conductor is prevalent within the copper wire industry as it marries steel's high tensile strength with Copper's conductivity and corrosion resistance.

Advantages

CCS products can be utilized for grounding applications, including connecting ground rods to metal structures, lightning arrestors, and power installations. Additionally, copper-plated steel can efficiently transmit power.

Beyond that, it features impressive resistance to fatigue and tension.

Copper Clads Board/Laminate (CCL)

The copper-clad board originates from a reinforcing material thoroughly laminated with copper on both sides after being immersed in resin.

These boards display exceptional heat resistance and can endure punched holes without breaking.

Advantages

CCL serves effectively as the foundational material for printed circuit boards (PCB). Its high conductivity enables the circuit to transport voltage across the board without risk of overheating, made possible by its "Copper on Steel" feature.

Furthermore, designers can easily etch circuit designs onto the board for use in FM transmitter circuits or various copper plating applications.

3. What's the Difference between Copper and Copper Clads?

Pure copper wires have long been recognized for their 97.6% conductivity and thus have habitually been favored for wiring and circuits. However, the high costs associated with copper led many manufacturers to explore alternatives, such as copper plating options that deliver similar benefits.

These benefits include:

• The recovery of Copper
• Controlled copper layer thickness
• Copper over a steel core

Moreover, copper-clad options are more affordable yet maintain comparable quality to pure Copper.

In the following section, we will elaborate on the differences between Copper and various copper-clad products.

Copper vs Copper Clads Aluminum (CCA)

While pure copper is typically the standard for electrical conductivity, many manufacturers now favor alternatives, including CCA as tracer wire.

The following outlines the differences:

Differences

Copper coated/clad aluminium employs an aluminium core enveloped by copper layers, while pure Copper consists solely of copper. CCA serves as a cost-efficient alternative, contrasting with the comparatively higher expense of pure copper. Additionally, CCA serves as bi-metal wiring, a characteristic not present in pure Copper.

Copper vs Copper Clads Steel

CCS specializes in electrical grounding, featuring a robust steel core coated in Copper to create a strong yet conductive electrical rod.

The differences between Copper and CCS are clear:

Differences

Copper Clad Steel showcases exceptional tensile strength and copper thickness, capable of enduring significant tension without fracturing. Conversely, pure Copper may break under excessive stress. CCS combines the durability of steel with Copper's resistive properties, providing a bi-metal solution tailored for grounding applications, distinct from pure Copper meant mainly for wiring.

Copper vs Copper Clads Boards/Laminates

Specific copper plated boards emerge from distinct materials encased in copper strips, while they typically serve one overarching function in the copper market.

Here are the key differences between Copper and copper-coated/clad boards:

Difference

Copper plated/clad boards are ideally structured as the foundational element of PCBs. Whether sourcing them or fabricating custom shapes, they typically feature a rectangular architecture that is adaptable to specific needs. In contrast, pure Copper predominantly focuses on wiring utilities.

4. What Products Is Copper Clads Suitable For?

The versatility of Copper clad allows for numerous applications.

Notable copper-clad products include wiring for Ethernet and home electrical setups, alongside circuit boards for devices such as televisions, mobile phones, radios, and a spectrum of other electronics, including copper-clad ground rods.

Final Words

Copper clad offers a valuable means of acquiring Copper's advantages without the associated costs.
