High-Performance Copper Clad Aluminum Plate: A Smart Solution for Modern Industry

What is a Copper Clad Aluminum Plate?
A copper clad aluminum plate (also known as CCA plate) is a bimetallic material formed by bonding a layer of copper to a core of aluminum through methods such as explosion welding or roll bonding. It combines the excellent conductivity of copper with the lightweight and cost-effective properties of aluminum.

 Key Properties of CCA Plates
Excellent electrical and thermal conductivity

Lightweight, about 40% less than pure copper

Strong metallurgical bonding between layers

Superior corrosion resistance with proper treatment

Cost-effective alternative to pure copper materials

How Copper Clad Aluminum Plate is Manufactured
The most common techniques for producing high-quality CCA plates are:

1: Explosion Welding
A high-energy detonation process that bonds copper and aluminum under extreme pressure without melting the metals. This technique forms a strong metallurgical interface.

2: Roll Bonding
Metals are rolled together under heat and pressure, producing a durable bond suitable for high-volume applications.

Baoji Shenao offers both explosion-welded and roll-bonded CCA plates, tailored to customer requirements in terms of thickness, width, and surface condition.

Applications of Copper Clad Aluminum Plates
CCA plates are used across a range of industries where cost efficiency, conductivity, and weight reduction are essential:

1: Electronics and Power Distribution
Busbars

Transformer windings

Circuit board shielding

Battery current collectors

2: New Energy and Battery Systems
Electric vehicle (EV) battery connectors

Solar panel backplanes

Energy storage system terminals

3: Construction and HVAC
Lightning protection systems

Heat exchangers

Decorative architectural panels

Google’s People Also Ask: Copper Clad Aluminum Plate FAQ
Is copper clad aluminum better than pure copper?
It depends on the application. CCA offers similar conductivity at a much lower weight and cost, making it ideal for large-scale, cost-sensitive applications like EV batteries or busbars.

Is copper clad aluminum conductive?
Yes. While slightly less conductive than pure copper, a CCA plate maintains over 70% conductivity with reduced weight, making it efficient and economical.

Is copper clad aluminum plate corrosion-resistant?
When manufactured properly and with appropriate surface treatments, CCA plates provide excellent corrosion resistance, especially in indoor and controlled environments.

How do I choose the right CCA plate thickness ratio?
Common copper-to-aluminum thickness ratios are 10:90, 15:85, and 20:80. Your choice should depend on the current-carrying capacity, mechanical strength, and application needs.
