Battery pack welding tolerates no surprises: a tab with inconsistent chemistry or thickness shows up as an uneven weld nugget or a weak joint. This customized high purity nickel strip is produced under ISO 9001 quality-system control in our nickel-only plant, from N4 (NP1) with Ni+Co of 99.9% or higher. Low electrical resistivity keeps weld current stable, and custom thickness, width and length let the strip match your tab design exactly. Every coil is composition-tested per batch and can ship with EN 10204 3.1 documentation.
| Parameter | Value | Note |
|---|---|---|
| Thickness | 0.05-0.5 mm | custom per drawing |
| Width | 5-200 mm | custom per drawing |
| Length / coil | Per drawing | continuous strip per order |
| Temper | M / 1/4H / 1/2H | per drawing |
| Tolerances | Per ASTM B162 / GB/T 2072-2020 | exact values per drawing |
MOQ: 3 kg for N4 high-purity strip; 5 kg for standard grades. Sample policy: free 0.5 kg for N6 / Ni200; N4 and Ni201 samples are charged, refundable with first orders above 50 kg.
Spot welding quality is governed by the resistance at the weld interface. Pure nickel strip delivers a clean, low-resistance contact surface with no coating layer to interfere with current transfer, so weld nuggets form consistently run after run. Electrical resistivity anchors the performance: 0.096 μΩ·m at 20°C. Actual welding parameters depend on tab geometry and the welder used; joint trials are recommended before series production.
Example for a tab of 0.15 mm thickness and 8 mm width (cross-section 1.2 mm²), resistivity 0.096 μΩ·m:
| Parameter | Value | Note |
|---|---|---|
| Resistance per 100 mm length | 8.0 mΩ | calculated R = ρ·L/A |
| Voltage drop at 5 A per 100 mm | 40 mV | calculated |
| Current at 4 A/mm² (assumed) | 4.8 A | assumed current density |
| Current at 8 A/mm² (assumed) | 9.6 A | assumed current density |
Values calculated with stated assumptions — for reference only, confirm against your pack design.
Impurities in the strip become inclusions in the weld nugget, and inclusions become weak joints. N4 with Ni+Co of 99.9% or higher keeps the impurity budget below 0.1%, and per-batch composition testing ensures every reel carries the same chemistry — the basis of repeatable weld quality.

Changzhou DLX Alloy Co., Ltd. has manufactured nickel alloys since 2002 in a 12,000 m² factory rated at 1,200 tonnes per year. For battery welding strip, material consistency is weld quality: the same chemistry, the same temper, the same surface from reel to reel. Our nickel-only line and per-batch verification with EN 10204 3.1 documentation keep every coil aligned to the drawing — the foundation of repeatable spot welds in your production line.
A: Pure nickel gives a clean, low-resistance contact surface with no coating layer to interfere with current transfer, so weld nuggets form consistently. Electrical resistivity anchors the performance at 0.096 μΩ·m (20°C).
A: Thickness (0.05-0.5 mm), width (5-200 mm), length and coil form are manufactured per drawing, with tolerances locked at order confirmation.
A: Yes for N4 (NP1), with Ni+Co of 99.9% or higher. Composition is tested per batch and can be documented with an EN 10204 3.1 material certificate.
A: 3 kg for N4 high-purity strip; 5 kg for standard grades. Sample policy: free 0.5 kg for N6 / Ni200; N4 and Ni201 samples are charged, refundable with first orders above 50 kg.
