Production Process For Copper Clad Aluminum Busbar
- 1 Material Selection: High-purity aluminum rods (99.7%) + Oxygen-free copper strips (99.9%)
- 2 Coating: Copper strips are wrapped around the aluminum core and then welded at high temperature to form a composite billet.
- 3 Stretching: Through multiple molds, the copper-coated aluminum conductor is stretched to obtain the specified specifications.
- 4 Tempering: Low-temperature tempering treatment to enhance the flexibility and conductivity of the conductor.
- 5 Testing: Full-process online testing (copper layer thickness, conductivity, dimensional accuracy).

FAQ For Cu Clad Al Busbar
They can completely replace pure copper in medium and low voltage, short-distance transmission scenarios (such as home wiring, control cables), and offer better cost performance; for long-distance high-voltage transmission, it is recommended to select the model based on actual needs.
The outer copper layer has excellent welding properties and can be welded using methods such as soldering or argon arc welding, ensuring a secure and non-detachable connection.
Standard specifications are delivered within 5–7 working days of order placement, while custom specifications take 10–15 working days.
The minimum copper layer thickness is ≥0.1mm, and it can be customized to thicker specifications based on your specific application requirements and performance needs.
We offer tin plating and nickel plating surface treatments to enhance welding properties and improve corrosion resistance, ensuring longer service life in demanding environments.
Yes. With a working temperature range of -40℃ to 150℃ and a neutral salt spray test result of ≥48 hours without rusting, the Cu Clad Al Busbar is well-suited for both indoor and outdoor applications in demanding conditions.
