One Side Pure Cu, One Side Pure Ni
Product Description
Our copper nickel clad plate is engineered for OEM lithium battery supply chains, combining one side pure copper with one side pure nickel in a high-strength metallurgical bond. This design maximizes electrical and thermal conductivity while providing a nickel surface optimized for reliable welding in battery assembly.
Widely used as lithium battery tabs, terminals, and interconnects, the clad plate helps reduce internal resistance, improve heat dissipation, and enhance overall battery performance and safety. Fully customizable for thickness ratio, dimensions, and temper to meet the exact requirements of EV, energy storage, and consumer lithium battery manufacturers.
Rapid Export Fulfillment: Integrated slitting and packing lines ensure your order is ready for port delivery within days, not weeks.
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.
