21700 lines start with 0.15 mm more often than any other gauge — and a trial coil is the fastest way to prove it on your welder. Our 0.15mm nickel strip for 21700 cells is produced from Ni200 (≥99.2% Ni) in 2P/3P/4P patterns, with custom widths locked against your drawing. Start with a free N6/Ni200 sample, confirm the strip on your line, then scale — 5 kg MOQ, 3-7 day delivery for small lots and 7-15 days for standard production, from our ISO 9001 certified nickel-only line.
Strip is produced at 0.15 mm as specified (within the 0.05-0.5 mm range) in 2P/3P/4P patterns for 21700 cells, with battery widths of 2-15 mm. Pattern geometry, pitch and tolerances are confirmed against the drawing before production and locked in the batch record.
- Hot-sale 0.15 mm gauge — the starting gauge for 21700 lines, held to drawing tolerance.
- Ni200 purity — ≥99.2% Ni, the battery standard grade.
- 2P/3P/4P patterns — pre-punched for 21700 cells, ready to weld.
- Sample first, low MOQ — N6/Ni200 free samples of 0.5 kg; 5 kg MOQ.
- Documented supply — EN 10204 3.1 MTC, ISO 9001 certified; 3-7 days small lots, 7-15 days standard.
0.15 mm balances cross-section and weld energy for typical 21700 pack currents: enough section to carry the current, thin enough to weld without excess heat. It is the gauge most pack lines qualify first, and it is held to drawing tolerance batch after batch.
Ni200 (≥99.2% Ni) is the default battery strip grade: full ductility for forming, low resistivity of 0.096 μΩ·m for consistent welds, and the grade most battery supply chains already specify.
2P/3P/4P patterns connect 21700 cells in parallel groups, with pitch and available space set to the pack layout. Patterns are punched to the drawing and checked for burr and dimensional accuracy per batch.
Qualification usually starts with a 0.5 kg sample: N6/Ni200 samples are free, Ni201/N4 samples are charged and refunded on a first order of 50 kg or more. The sample geometry is produced per drawing, so the production run matches the coil you tested.
| Grade | Ni Content | Best Application | Reference Price (FOB, USD/kg) |
|---|---|---|---|
| N4 (NP1) | ≥99.9% | Vacuum electronics | 420-480 |
| Ni201 | ≥99.0% | High-temp service | 350-390 |
| Ni200 | ≥99.2% | Battery, chemical | 340-380 |
| N6 (NP2) | ≥99.5% | Industrial corrosion | 300-340 |
The bands above are indicative for standard strip sizes. Pattern products are quoted per drawing — pattern geometry, grade, thickness and quantity determine the final price.

Quality control starts at the melt: raw material composition is verified against UNS N02200 before rolling, then every batch is gauged for thickness, pattern geometry, width and surface condition, and checked for burr against the drawing. Batch records link each order back to the melt, and EN 10204 3.1 mill test certificates ship with every consignment.
- ASTM B162 — nickel and nickel alloy plate, sheet and strip
- GB/T 2072-2020 — nickel and nickel alloy strip
- EN 10204 3.1 mill test certificates accompany shipments
Material data on this page follows ASTM B162 and GB/T 2072-2020; corrosion and application guidance references nickel industry literature (Nickel Institute; ASM Specialty Handbook: Nickel, Cobalt, and Their Alloys). Batch-level composition and geometry are verified against mill test certificates (EN 10204 3.1) and in-house inspection records.
Strip is supplied in rolls or cut lengths, edge-protected and moisture-wrapped, then packed in cartons and export wooden cases. Documentation — mill test certificates, batch records and packing lists — accompanies every order. Small lots ship in 3-7 days; standard production in 7-15 days from confirmed drawing.
The fastest way to judge a strip supplier is the first coil — and the second should match it exactly. DLX Alloy has run a nickel-only line since 2002 — 12,000 m² of floor space, 10,000 t/yr total capacity, ISO 9001 certified and SGS audited — rolling 0.15 mm battery strip in Ni200 and Ni201, with per-batch composition analysis and EN 10204 3.1 mill test certificates on every shipment.
