Custom Nickel Aluminum Clad Strip | Bimetal Solution for Battery Tabs & Lightweight Electrical Connectors

Custom Nickel Aluminum Clad Strip

Introdução

1. Nickel Aluminum Clad Strip is a high-performance bimetal composite created by metallurgically bonding a nickel layer to an aluminum core using advanced roll-bonding and diffusion technology. This material effectively solves the technical challenge of joining dissimilar metals by providing a stable, low-resistance interface that prevents the formation of brittle intermetallic compounds. It combines the superior corrosion resistance and excellent weldability of nickel with the low density and high thermal conductivity of aluminum, offering a lightweight and cost-effective alternative to solid nickel or copper-based components.

2. Our Ni-Al clad strips are fully customizable to meet your specific engineering needs, including adjustable thickness ratios (e.g., 20/80 or 10/90), total thickness, and strip width. They are predominantly used as transition tabs in lithium-ion and LiFePO4 battery packs, EV battery modules, and energy storage systems, enabling reliable ultrasonic or laser welding between aluminum electrodes and nickel-plated busbars. With excellent formability for stamping, bending, and high-speed automated processing, these strips ensure consistent electrical performance and long-term durability in demanding power electronics and automotive applications.

   Especificações

   Tipo	Nickel‑Aluminum Clad Strip / Coil / Ribbon / Bimetal Composite
   Structure	Metallurgically bonded Ni–Al composite: typically Ni/Al or Al/Ni/Al layered structures produced by solid‑state roll‑bonding and diffusion bonding
   Material Grade	Commercial‑purity or high‑purity nickel (e.g., Ni200/201 or equivalent) clad to electrical/structural aluminum (e.g., 1xxx, 3xxx series such as AA1050, AA1060, AA1100, AA3003)
   Ni/Al Ratio (Volume/Area)	Customizable nickel and aluminum thickness ratio (e.g., 5/95, 10/90, 20/80, 30/70, 50/50 etc.), optimized for welding, conductivity, weight, and cost
   Electrical & Thermal Conduct.	Aluminum core provides low density and good electrical/thermal conductivity; nickel layer offers stable contact resistance and reliable weldability to nickel‑, steel‑ or copper‑based busbars
   Formulário	Narrow strip, coil, ribbon, or flat stock; supplied as continuous coils, cut‑to‑length strips, or pre‑processed tabs and connector parts
   Gama de espessuras	Customizable total thickness, typically from about 0.05 mm to 2.0 mm (or more on request); individual Ni and Al layer thicknesses adjustable according to design and current‑carrying or welding requirements
   Width & Length	Strip width typically from a few millimeters up to about 200–300 mm (depending on thickness); supplied in coils or fixed cut lengths according to customer specifications
   Bonding Method	Solid‑state roll bonding followed by thermal treatment/diffusion bonding to create a continuous, high‑strength metallurgical interface between nickel and aluminum layers
   Interface Quality	High bonding strength, uniform cladding, low interface resistance, and good peel strength suitable for high‑reliability battery, busbar, and power‑electronics applications
   Mechanical Properties	Good strength‑to‑weight ratio and formability; suitable for slitting, stamping, bending, and tab forming; nickel surface improves wear and contact durability at welded or clamped joints
   Density & Cost Balance	Bimetal design reduces the use of solid nickel while maintaining a nickel working surface, lowering both weight and cost compared with all‑nickel strips or connectors
   Surface Finish	As‑rolled, bright‑annealed, matte, or brushed; controlled roughness on Ni or Al side to improve welding, bonding, or coating adhesion
   Surface Treatment	Degreased and cleaned as standard; optional oxidation‑control treatment, special cleaning for battery‑grade use, or pre‑plating on the nickel side (e.g., tin) if required by the joining process
   Weldability & Joining	Designed for ultrasonic welding, resistance welding, laser welding and spot welding; good compatibility with common joining of battery tabs, busbars, and laminated conductors
   Corrosion & Wear Resistance	Nickel layer provides improved resistance to oxidation, corrosion, and mechanical wear, helping protect the aluminum substrate in typical battery and power‑electronics environments
   Dimensional Tolerances	Tight control of thickness, width, and flatness to ensure stable automated feeding, consistent welding results, and reliable electrical performance
   Standards & Reference	Manufactured with reference to relevant nickel and aluminum material standards (e.g., ASTM/EN/GB for base metals and composite strip quality); specific grades and tolerances available on request
   Application Range	Lithium‑ion and LiFePO₄ battery tabs, EV and energy‑storage pack connections, aluminum–copper transition joints, busbar connections, power‑electronics interconnects, and other lightweight electrical conductors
   Processing Capability	Supports slitting, shearing, precision stamping, progressive die forming, punching, tab forming, and CNC profiling; suitable for high‑volume automated production of battery and connector components
   Customization	Tailored Ni/Al structure, thickness, width, coil inner/outer diameter, mechanical properties, surface finish, and pre‑stamped/weld‑ready geometries according to drawings or CAD files
   Packaging	Supplied in sealed coils or bundled strips with edge protection; anti‑corrosion wrapping and reel/wooden‑case packaging available for safe transport and long‑term storage
