Difference Between Electroplating And Cold Rolling Processes for Copper-Clad Steel

Copper-clad steel is a composite material combining steel’s strength with copper’s conductivity. Two primary methods are used to produce it: electroplating and cold rolling. Understanding their differences helps industries choose the right solution for their needs.

1. Electroplating Process
Electroplating involves depositing a copper layer onto a steel substrate through an electrochemical reaction. The steel is immersed in a copper-ion solution, and an electric current bonds the copper to the surface. This method creates a thin, uniform copper layer but may result in weaker adhesion and higher porosity, limiting its durability in harsh environments.

2. Cold Rolling Process
Cold rolling mechanically bonds copper and steel under high pressure without heat. Multiple layers of copper and steel are compressed through rollers, forming a seamless, dense composite. This method ensures stronger adhesion, higher conductivity, and superior corrosion resistance. It’s ideal for high-performance applications like refrigeration systems, construction engineering, military and other fields.

Key Advantages of Cold Rolling:

Durability: Robust bonding resists peeling.

Cost-Efficiency: Suitable for mass production.

Customization: Thickness and ratios can be tailored.
