One Side Pure Cu, One Side Pure Ni
Product Description
Our wholesale nickel copper composite sheet is a premium bimetallic material with one side pure nickel and one side pure copper, engineered specifically for power electronics applications. Produced through advanced metallurgical bonding technology, it creates a strong, reliable interface that leverages copper’s exceptional electrical and thermal conductivity together with nickel’s superior weldability and corrosion resistance.
This nickel copper composite sheet is widely used in power modules, IGBT modules, battery systems, busbars, and other high-current power electronics components. Available in wholesale quantities with flexible customization options, it helps manufacturers reduce resistance, improve heat dissipation, and enhance overall system reliability.
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.
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
Permanent Atomic Fusion: Our high-pressure cold-rolling technology ensures the nickel and copper layers are inseparable, maintaining a shear strength of ≥150 MPa suitable for high-vibration automotive and industrial use.
Superior Conductivity Synergy: Leveraging a pure copper base (≥100% IACS), the clad plate achieves conductivity ≥88% IACS, providing a high-speed electrical highway with minimal resistance.
Weld-Ready Nickel Surface: The pure nickel side (≥99.6%) offers a stable, oxide-free interface for high-reliability fiber laser, ultrasonic, and spot welding to cell terminals or busbars.
Passive Thermal Management: With thermal conductivity ≥330 W/m·K, the copper core acts as a high-speed heat sink, preventing hotspots during high-current discharge or fast charging.
