Wide Temperature Range Flexible High Purity Pure Nickel Strip for Precision Battery and Industrial Applications

Engineered for precision and durability, our pure nickel strip is the perfect choice for welding and battery manufacturing applications. Its excellent weldability and thermal conductivity — 70.2 W/m·K for Ni200 — make it an essential material for spot welding electrodes and battery tabs. With a smooth surface finish and tight dimensional tolerances, this strip ensures seamless integration into your manufacturing processes. Four grades (N4, N6, Ni200, Ni201) cover the purity ladder from ≥99.9% to ≥99.2%, thickness runs 0.05-0.5mm and width 5-200mm, and every coil carries EN 10204 3.1 MTC with heat traceability. Thickness and dimensions can be customized to meet customer requirements.

• Excellent weldability — essential for spot welding electrodes and battery tabs.
• High thermal conductivity — 70.2 W/m·K (Ni200) for efficient heat management in welding.
• Wide temperature range — melting point 1435-1446°C for heating elements and high-temp service.
• Smooth surface finish and tight dimensional tolerances — seamless integration into manufacturing.
• Customizable thickness and dimensions — matched to your drawing, with EN 10204 3.1 MTC.

Pure nickel strips are extensively used in battery manufacturing, especially for connecting cells in battery packs. Their excellent conductivity and corrosion resistance make them ideal for high-performance batteries, including those in electric vehicles (EVs) and portable electronics. In the electrical industry, nickel strips serve as key components in various equipment, providing reliable connections and enhancing conductivity. They are also used in electronic devices for connectors, grounding straps and shielding applications, applied as protective coatings on other metals against corrosion, used in heating elements for appliances such as toasters, ovens and industrial furnaces, and employed in chemical and aerospace industries where corrosion resistance, strength and durability are required.

Among nickel materials, pure nickel sits at the low-resistance, high-conductivity end of the family — resistivity of 0.096 μΩ·m at 20°C and thermal conductivity of 70.2 W/m·K for Ni200, the combination battery tabs and welding electrodes depend on.

Strip is a dimensional product: thickness and width define the component. Standard thickness runs 0.05-0.5mm and width 5-200mm, with slit widths and tolerances confirmed per drawing before production. Edge quality and width consistency are inspected along the length of every coil.

Strip is supplied in temper states matched to its use: annealed for forming and stamping, with the documented baseline of ≥462 MPa tensile strength, ≥35% elongation and 90-120 HB hardness. Specify the required temper on the drawing and the strip is processed accordingly.

Indicative FOB China reference prices for strip; final quotation per grade, size, quantity and temper.

Source: DLX product catalog. N4/N6 per GB system; Ni200/Ni201 per ASTM system.

The 5 kg minimum applies to standard strip grades; N4 (≥99.9%) high-purity orders qualify for the 3 kg MOQ per the grade-based schedule.

Quality control for strip follows the form, not a generic checklist:

• Incoming: raw nickel verified per heat before processing.
• In-process: thickness, width and edge quality checked along the coil; surface inspected.
• Final: chemistry verified per heat; mechanical properties sampled per heat.
• Documentation: EN 10204 3.1 MTC with heat number, test results and full traceability.

Ni200/Ni201 strip is manufactured and tested to ASTM B162; N4/N6 follow GB/T 2072-2020. Testing methods and acceptance criteria follow the drawing specification and applicable standards.

Strip is supplied in coils with protective wrapping against transit damage and surface marking. Production lead time is 7-15 days after drawing and grade confirmation. Every order ships with the complete export documentation set: packing list, commercial invoice and mill test certificate.

Pure nickel strip plays a structural role in battery packs — connecting cells, carrying current, surviving welding — and Changzhou DLX Alloy Co., Ltd. has supplied nickel strip to that industry since 2002. The nickel-only 12,000 m² line controls composition and dimensional consistency from melt to coil, and every delivery carries EN 10204 3.1 MTC with heat traceability, so battery makers can qualify the material once and scale. From EV packs to portable electronics, the strip that connects cells is the strip DLX ships.

Pure nickel strips connect cells in battery packs — especially in EVs and portable electronics — where their conductivity, corrosion resistance and weldability are essential for reliable connections.
