Product Description
Our pure nickel strip N4 N6 combines ≥99.6–99.9% nickel content with soft annealed (soft temper) processing to deliver optimal electrical conductivity and mechanical ductility. Equivalent to Ni200/Ni201 (ASTM B162), the material features low electrical resistivity (approximately 7.6–8.5 µΩ·cm / ~25% IACS), density of 8.89 g/cm³ and melting range of 1435–1446 °C. Soft temper hardness (typically HV 90–140) ensures the strip sits flat on cell terminals, enabling deep, reliable spot welds without excessive heat input that could damage lithium cells. Ideal for high-drain UAV drone packs, these battery interconnect strips reduce I⊃2;R losses, improve power delivery and support long-term reliability in vibration-prone environments.
Key Material Advantages:
Exceptional electrical conductivity and low resistivity for efficient current flow
High corrosion resistance in various environments, including caustic and oxidative conditions
Excellent weldability and solderability for automated electronics assembly
Superior ductility and formability for custom nickel strip fabrication
Low gas content and vapor pressure, ideal for vacuum and high-reliability applications

FAQ
N6 (Ni200) offers ≥99.6% purity and excellent all-round conductivity/cost balance for most battery packs. N4 (Ni201) has higher purity (≥99.9%) and lower carbon content, making it more resistant to embrittlement above ~315 °C and preferred for higher-temperature or ultra-critical applications.
Soft temper provides superior formability, sits flat on cell terminals and allows deep weld penetration at lower energy levels, reducing the risk of damaging sensitive lithium cells while delivering strong, low-resistance joints that survive vibration.
Yes. Pure nickel strip delivers significantly lower electrical resistance, better corrosion resistance and more consistent long-term performance under high current, whereas plated steel can introduce higher impedance and potential plating failures.
Common choices are 0.10–0.20 mm thickness depending on continuous and peak current; widths are selected according to parallel group configuration (e.g., 7 mm, 10 mm, 27 mm for 2P layouts). Custom sizes are available to match specific pack designs.
Yes. Soft-temper pure nickel strip is specifically optimized for resistance spot welding. Proper electrode pressure, pulse energy and surface cleanliness yield strong, low-resistance bonds suitable for high-reliability UAV packs.
