ISO9001 and ROHS Certified High Electrical Conductivity Pure Nickel Strip for Battery Packs

Our pure nickel strip offers exceptional conductivity and corrosion resistance, making it ideal for various electrical applications. With its high purity and uniform thickness, this strip ensures consistent performance in battery tabs, electrical contacts, and other electronic components. Whether used in aerospace, automotive, or consumer electronics, our pure nickel strip delivers reliability and durability. Resistivity sits at 0.096 μΩ·m at 20°C — low among nickel materials — and thermal conductivity at 70.2 W/m·K for Ni200. Thickness runs 0.05-0.5mm and width 5-200mm with slit widths per drawing, and every coil carries EN 10204 3.1 MTC with heat traceability.

• Exceptional conductivity — 0.096 μΩ·m at 20°C, low among nickel materials.
• Uniform thickness and high purity — consistent performance in battery tabs and contacts.
• Good spot welding — stronger battery spot welding, longer discharge time.
• Wide battery coverage — 18650/21700/26650/32650/32700 packs, 1P-9P configurations.
• Corrosion resistance and reliability — used in aerospace, automotive and consumer electronics.

Strip for battery packs is specified by cell size and connection pattern. DLX supplies configurations from 1P to 9P for 18650, 26650, 32650, 21700 and 32700 battery packs, with available spaces of 18.5mm, 19mm, 19.5mm and 20.2mm. Products are widely used in energy storage batteries, new energy vehicles, electric bicycles, solar street lights, power tools and other energy products.

Low resistance means longer battery discharge time and stronger spot welding. Resistivity is 0.096 μΩ·m at 20°C — low among nickel materials — with thermal conductivity of 70.2 W/m·K for Ni200, melting point of 1435-1446°C and Curie temperature of 358°C.

Thickness runs 0.05-0.5mm with hot sellers of 0.15mm and 0.2mm; width covers 5-200mm with slit widths and tolerances confirmed per drawing. Edge quality and width consistency are inspected along the length of every coil.

Every coil follows a controlled eight-step line: raw material selection of high-purity nickel, melting and casting in a controlled environment to prevent contamination, hot rolling to reduce thickness, cold rolling at room temperature, annealing to relieve internal stresses and improve ductility, slitting and cutting to specific widths and lengths, surface treatment through cleaning, polishing or coating, and final quality inspection of purity, thickness, width and mechanical properties.

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; final inspection covers purity, thickness, width and mechanics.
• 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.

Nickel strip is packaged in rolls with polybag protection and packed into cartons, protecting the surface during transit. 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.

Battery strip is made in the stamping and slitting line as much as in the melt shop. Changzhou DLX Alloy Co., Ltd. equips that line with imported stamping machines, Sodick equipment and a battery-industry mold inventory of more than 2,000 sets, with independent mold development — so 1P-to-9P configurations are stamped clean and consistent. All strip materials are degreased and processed with dry-punching technology to keep the product clean. That equipment base, on a nickel-only 12,000 m² line, is what lets DLX supply battery packs from 18650 to 32700 with reliable, weldable strip.

18650, 21700, 26650, 32650 and 32700 battery packs, with configurations from 1P to 9P and available spaces of 18.5mm, 19mm, 19.5mm and 20.2mm.

Thickness runs 0.05-0.5mm with hot sellers of 0.15mm and 0.2mm; width covers 5-200mm with slit widths and tolerances confirmed per drawing.

Resistivity is 0.096 μΩ·m at 20°C — low among nickel materials — delivering longer battery discharge time and stronger spot welding.

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

Every delivery includes EN 10204 3.1 MTC with heat number and batch traceability, backed by ISO9001 and SGS certification. Strip meets ASTM B162 (Ni200/Ni201) and GB/T 2072-2020 (N4/N6).
