Copper clad steel sheets
PRODUCT INTRODUCTION
What is a Copper Clad Steel Sheet?
The copper clad steel sheet, also referred to as a copper steel clad plate, is a revolutionary bimetallic composite material created by explosion bonding or explosion-roll bonding techniques. This advanced cladding process ensures that the copper layer is permanently bonded to the steel base, forming an inseparable and uniform metallurgical connection.
The result is a composite material that combines the conductivity, corrosion resistance, and aesthetics of copper with the strength, formability, and affordability of steel. It is increasingly used in critical engineering applications where dual performance characteristics are essential.

Manufacturing Process
-
Material Inspection & Selection – All raw copper and steel undergo spectral analysis.
-
Surface Cleaning & Treatment – To ensure bonding quality, all surfaces are precisely cleaned.
-
Explosive Bonding – Plates are bonded with precisely calculated detonation energies.
-
Hot Rolling (Optional) – Enhances surface flatness, uniform thickness, and bond strength.
-
Annealing & Finishing – Relieves internal stress and prepares the final surface.
-
Final Inspection & Testing – Ultrasonic testing, shear strength, corrosion resistance, and dimensional checks.
We strictly adhere to ASME, ASTM, JIS, and GB/GBT standards, and our processes are ISO9001:2000, PED, and ABS certified.
Cladding Technique: Explosive Bonding Method
JL CLAD METALS adopts explosive bonding—a high-energy cold welding technique that ensures metallurgical bonding between titanium and copper without melting the base metals. This results in:
- Excellent interfacial strength
- No intermetallic compounds
- Zero porosity and high reliability
- Ability to bond dissimilar metals that are otherwise unjoinable via welding
This method preserves the mechanical integrity of both metals and provides a long-lasting, durable composite.
