One Side Pure Cu, One Side Pure Ni
Product Description
Our industrial Cu-Ni clad plate is a high-purity bimetallic composite with one side pure copper (Cu) and one side pure nickel (Ni). Produced through advanced metallurgical bonding technology, it delivers the high electrical and thermal conductivity of copper together with the excellent weldability, corrosion resistance, and surface stability of nickel.
This high-purity copper nickel clad plate is specially optimized for energy storage applications, including lithium-ion battery systems, stationary energy storage (ESS), and industrial high-current interconnects. It enables lower internal resistance, improved thermal management, and reliable long-term performance in demanding energy storage environments.
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.
