Tuling’s Copper Clad Aluminum Busbar
The copper coating on aluminum ensures a high quality performance of our CCA (copper clad aluminum) bars. These busbars weigh 2 to 2.5 times less than the pure copper bars of the same length. Our copper cladded bars offer more than 98% conductivity in a 64% reduced volume.
Tuling CCA busbars are corrosion and wear resistant. Also, we can manipulate hardness properties via tempering and annealing. Our heat-treated CCA busbar grades are O, H28, H26, and H24.
Tuling Copper Clad Aluminum Bus Bar Features
The combination of aluminum and copper ensures high electrical performance.
We can keep the busbar weight to a minimum by integrating aluminum and copper.
Our copper-clad aluminum bars have excellent flexibility and tensile strength.
Save 40% of your budget with Tuling CCA bars without compromising quality.

Tuling Copper Clad Busbar Material Options
Our energy-saving copper-clad busbars are made of pure copper and aluminum. Our preferred grades are,
- Copper T2
- Aluminum (1050/1060/1070/1100)
We can influence the copper and aluminum composite ratio between 10% to 35%. Busbar conductivity and performance depend on this composition ratio.
Wide Usage of Our Copper Clad Aluminum Busbar
Our copper-clad busbars are mostly used in power transmission and distribution systems due to their high conductivity. Besides, our CCA bars are also found in,
- Electric vehicle charging facilities
- Architecture and Buildings
- Metallurgy industry
- High and low-voltage electrical equipment
- Electronic communication equipment
- Automation and industrial fields
Manufacturing Process of Tuling Copper Clad Aluminum Busbar
At Tuling, we utilize solid-liquid processing technology to manufacture copper-clad aluminum bars. This process helps us to permanently wrap the copper layer around an aluminum core in an oxygen-free environment.
Our upgraded cladding technology allows us to produce a firm bond between aluminum and copper without any defects and cracking. These bus bars are flexible enough to cut, bend, and punch.
Tuling Copper Clad Aluminum Bar Fabrication Capabilities
Our production floor has upgraded machines and over 50 presses to produce CCA bars of your specifications. We have facilities for bending, forming, drilling, milling, welding, plating, etc. Our precise machining technology allows us to control the dimensional tolerance down to ± 0.001’’.
We can make copper-clad aluminum bus bars with round and square corned edges. Our products have GB/T 30586-2014 and ASTM B1005 − 17 certifications.
Our copper-coated aluminum bars can perform well in highly heated environments. According to our test results, the copper clad maintains firm bonding up to 500 °C.
In terms of conductivity and performance, you should use aluminum bus bars with metal platings, such as nickel, silver, or tin. But copper-clad aluminum is a logical choice when budget and weight are your main considerations.
