Copper-Clad Steel Manufacturing Process: Precision & Quality Control

Copper-clad steel is a high-performance composite material widely used in electrical, automotive, and construction industries. Its production involves multiple critical stages to ensure durability, conductivity, and corrosion resistance.

1. Cladding

After rigorous raw material inspection, the base steel and copper overlay are laminated into double-layer or triple-layer composite plates, customized to meet specific customer requirements.

2. Annealing

This heat-treatment process adjusts the material’s hardness and elongation, ensuring optimal physical properties for industrial applications.

3. Precision Rolling

A high-tolerance rolling process refines the material to meet strict thickness and surface quality standards, enhancing performance in precision engineering.

4. Cleaning

Chemical treatments remove surface residues, restore natural copper color, and apply passivation to improve corrosion resistance.

5. Temper Rolling

This step eliminates the yield plateau effect, restoring flatness and mechanical properties for consistent performance.

6. Slitting

Final cutting ensures the material meets exact customer-specified widths, ready for industrial use.
