One Side Pure Cu, One Side Pure Ni
Product Description
Our bulk pure Cu Ni clad sheet is a high-performance bimetallic composite with one side pure copper (Cu) and one side pure nickel (Ni), engineered for electric vehicle (EV) battery applications. Produced through advanced roll-bonding technology, it forms a permanent metallurgical bond that combines copper’s exceptional electrical and thermal conductivity with nickel’s superior weldability and corrosion resistance.
This pure copper nickel clad sheet is optimized for high-volume EV battery manufacturing, offering significantly lower resistance than pure nickel while enabling reliable spot welding on the nickel side. It is widely used for negative electrode tabs, busbars, and interconnects in lithium-ion battery packs for electric vehicles, supporting higher current capacity, better heat dissipation, and improved battery efficiency.
Superior Processing Performance: Optimized for high-speed automated production, providing consistent flatness and edge quality that reduces machine downtime.
Dual-Metal Synergy: Eliminates the need for transitional plating or mechanical clamping, simplifying busbar design and improving reliability.
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
High-current battery parts can accumulate heat at contact points, welded areas, and narrow conductive paths. The copper layer helps distribute heat away from localized hot spots, while the nickel layer adds a stable functional surface for assembly-facing applications.
The pure nickel surface is suitable for battery component designs requiring welding, soldering, or other joining processes. It also helps protect the copper-facing function from direct environmental exposure where surface oxidation or corrosion resistance is a concern.
Material temper can be selected according to the planned forming operation. This allows the clad sheet to be adapted for flat blanks, bent connector parts, shaped terminals, and precision-stamped battery hardware.
The Cu–Ni clad construction is intended to keep the nickel and copper functions in one integrated material system. For projects involving repeated vibration, assembly pressure, or temperature variation, bond integrity requirements should be defined in the buyer’s drawing and inspection plan.
Power Electronics: Critical for IGBT baseplates, heat sinks for power transistors, and high-frequency inverter components.
Telecommunications: Applied in high-density connectors, microwave communication shielding, and power distribution modules.
Aerospace & Defense: Ideal for lightweight, high-reliability electronic housing and current-carrying components in aircraft systems.
Semiconductor Packaging: Used as lead frames and substrate materials for high-power LED modules requiring rapid heat dissipation.

FAQ
It is a bimetal sheet made from one pure nickel side and one pure copper side. It is not a conventional copper-nickel alloy grade.
The copper side supports high-current transfer and heat spreading, while the nickel side provides a stable functional surface for joining and environmental resistance.
Yes. The ratio can be adjusted according to current capacity, required nickel-facing function, finished-part design, and cost target.
Yes. Thickness, width, length, clad ratio, temper, edge condition, and finished blank requirements can be reviewed against your drawing.
