One Side Pure Cu, One Side Pure Ni
Product Description
Our copper nickel clad sheet is a high-quality bimetallic composite with one side pure copper (Cu) and one side pure nickel (Ni). Manufactured through advanced roll-bonding or explosion-welding processes, it creates a strong metallurgical bond that combines the outstanding electrical and thermal conductivity of copper with the corrosion resistance, weldability, and surface durability of nickel.
This one-side copper one-side nickel clad sheet offers significantly higher conductivity than pure nickel while providing easy spot welding and protection against oxidation. It is widely used in lithium battery tabs, electronic connectors, busbars, and other applications requiring reliable high-current performance and long-term stability.
Perfect Dual-Side Functionality: Pure copper side for maximum current carrying and heat dissipation; pure nickel side for excellent spot welding, ultrasonic welding, and corrosion protection.
Strong Metallurgical Bond: Advanced roll-bonding technology ensures permanent, high-strength bonding with no risk of delamination during stamping, forming, or thermal cycling.
Optimized for Battery & Electronics Manufacturing: Specifically engineered for lithium-ion battery tabs, interconnects, and high-reliability electronic components, improving assembly efficiency and product lifespan.
Global Express Delivery: Partnered with top-tier couriers to ensure 7-20 day door-to-port or door-to-door fulfillment worldwide.
Certified Traceability: Digital MTCs and compliance documentation are provided instantly upon dispatch for every wholesale order.

Features & Applications
Metallurgical Fusion Integrity: The Ni and Cu layers are fused at the molecular level, ensuring zero delamination even under the high-frequency vibrations and thermal expansion of industrial applications.
Ultra-Low Contact Resistance: The metallurgical interface provides near-zero Z-axis resistance, significantly reducing voltage drops in high-capacity battery packs.
Weld-Ready Nickel Surface: The pure nickel layer (≥99.6%) is processed to ensure stable oxide-free laser and ultrasonic welding performance.
Superior Ductility for Stamping: Our annealed stock items support 180-degree bending and complex forming without surface cracking or interface failure.
EV Battery Busbars: Primary interconnect tags where the nickel side welds to cell terminals and the copper side carries high current.
Power Distribution Units: Bimetallic transition sheets for high-power relays, switches, and industrial circuit breakers.
Energy Storage Systems (BESS): High-current interconnects for large-scale grid storage modules where efficiency is paramount.
Marine Electronics: Transition joints for seawater-cooled power electronics that require both nickel’s corrosion resistance and copper’s flux.
Consumer Electronics: Ultra-thin bimetallic connectors for high-drain laptop, drone, and smartphone battery packs.

FAQ
A: It combines copper’s high electrical and thermal conductivity with nickel’s excellent weldability and corrosion resistance. This results in lower resistance, better heat management, and easier assembly compared with pure nickel, while offering improved surface durability over pure copper.
A: Yes. One-side copper one-side nickel clad sheets are widely used for LIB negative electrode tabs and interconnects because they provide high conductivity for current carrying and a nickel surface that enables reliable spot welding.
A: Absolutely. We offer flexible thickness ratios (for example, higher copper content for maximum conductivity) along with custom total thickness, width, length, and temper to match your specific application requirements.
A: The clad sheet features a strong metallurgical bond created by roll-bonding or explosion welding, ensuring high peel strength and resistance to delamination during forming, stamping, welding, or thermal cycling.
