One Side Pure Cu, One Side Pure Ni
Product Description
Our factory direct Cu-Ni clad metal plate is a premium bimetallic composite with one side pure copper and one side pure nickel, engineered for high bond strength and long-term reliability. Produced using advanced roll-bonding technology, the metallurgical bond between copper and nickel ensures exceptional peel strength and resistance to delamination.
This high bond strength copper nickel clad sheet combines the superior electrical and thermal conductivity of copper with the weldability and corrosion resistance of nickel. It is the ideal solution for battery manufacturers, electronics producers, and industrial users seeking consistent quality, competitive factory pricing, and customizable specifications.
Industrial-Grade High Purity & Bond Strength: High-purity materials with strong metallurgical bonding prevent delamination under high current, thermal cycling, and mechanical stress.
Dual-Metal Synergy: Eliminates the need for transitional plating or mechanical clamping, simplifying busbar design and improving reliability.
Proven Industrial Scale: 12,000 m² facility dedicated to dissimilar metal bonding, ensuring stable supply for multi-ton global contracts.
Fully Customizable OEM Supply: Flexible copper-to-nickel ratios, thickness, width, length, and surface finish available to match your production line and design specifications.
Total Quality Control: Integrated manufacturing from high-purity melting to precision slitting, ensuring 100% batch-to-batch consistency.

Features & Applications
Permanent Atomic Fusion: Our high-pressure cold-rolling technology ensures the nickel and copper layers are inseparable, maintaining a shear strength of ≥150 MPa suitable for high-vibration automotive and industrial use.
Superior Conductivity Synergy: Leveraging a pure copper base (≥100% IACS), the clad plate achieves conductivity ≥88% IACS, providing a high-speed electrical highway with minimal resistance.
Weld-Ready Nickel Surface: The pure nickel side (≥99.6%) offers a stable, oxide-free interface for high-reliability fiber laser, ultrasonic, and spot welding to cell terminals or busbars.
Passive Thermal Management: With thermal conductivity ≥330 W/m·K, the copper core acts as a high-speed heat sink, preventing hotspots during high-current discharge or fast charging.
EV Battery Interconnects: High-current interconnecting tags and busbars for electric vehicle battery modules and packs.
BESS Power Distribution: Durable transition plates for large-scale energy storage container systems.
Power Electronics Substrates: Heat spreader plates for IGBT and MOSFET modules in industrial inverters and DC-DC converters.
Renewable Energy Connectors: High-efficiency bimetallic interconnects for hydrogen electrolyzers and solar power systems.
Heavy-Duty Relays & Switches: Transition pads for industrial power distribution units where low resistance is paramount.

FAQ
A: High bond strength refers to the strong metallurgical bond between the copper and nickel layers, achieved through advanced roll-bonding. This ensures the clad plate resists peeling, delamination, and separation during forming, stamping, welding, and long-term use.
A: Factory direct supply offers competitive pricing, consistent quality control, shorter lead times, and the ability to customize thickness ratios, dimensions, and temper according to your exact requirements.
A: Yes. The one-side copper one-side nickel design is widely used for LIB negative electrode tabs and interconnects because it provides high conductivity for current flow and a nickel surface that enables reliable spot welding.
A: Absolutely. We offer flexible thickness ratios, total thickness, width, length, and temper options so you can optimize conductivity, weldability, and cost for your specific application.
