One Side Pure Cu, One Side Pure Ni
Product Description
Our pure nickel copper composite sheet is a high-performance bimetallic material with one side pure nickel and one side pure copper. Produced through advanced roll-bonding technology, it forms a permanent metallurgical bond that unites copper’s superior electrical and thermal conductivity with nickel’s excellent weldability, surface durability, and corrosion resistance.
As an OEM custom pure nickel copper composite sheet, it is specifically engineered for demanding applications such as lithium-ion battery tabs, high-current connectors, and precision electronics. The dual-side design enables efficient current carrying on the copper side while allowing reliable spot welding and protection on the nickel side, delivering optimal performance and manufacturing 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.

FAQ
A: It combines copper’s high electrical and thermal conductivity with nickel’s excellent weldability and corrosion resistance, resulting in lower resistance, better heat dissipation, easier assembly, and improved durability versus single-metal options.
Q2: Is this pure nickel copper composite sheet suitable for lithium battery tabs?
A: Yes. It is widely used for LIB negative electrode tabs and interconnects because the copper side provides high current-carrying capacity while the nickel side enables reliable and efficient spot welding.
Q3: Can you provide full OEM customization for this composite sheet?
A: Absolutely. We offer complete OEM customization including copper-to-nickel thickness ratio, total thickness, width, length, temper, surface finish, and packaging to exactly match your technical drawings and production requirements.
