Battery electronics are sensitive to magnetic fields — and strip with lower permeability keeps pack sensors reading clean. Our low magnetic permeability nickel strip is produced from Ni200/Ni201 pure nickel (≥99.2%/≥99.0% Ni) with low electrical resistivity of 0.096 μΩ·m, in battery widths of 2-15 mm with custom sizes locked against your drawing. Every batch is made on our own nickel-only line, inspected per batch and shipped with EN 10204 3.1 mill test certificates — 5 kg MOQ, 3-7 day delivery for small lots, 7-15 days for standard production.

Strip is produced in thicknesses of 0.05-0.5 mm (hot-sale 0.15/0.2 mm) and battery widths of 2-15 mm, with patterns produced per drawing. Pattern geometry, pitch and tolerances are confirmed against the drawing before production and locked in the batch record.

• Low magnetic permeability — reduced magnetic interference for pack electronics, relative to nickel-iron alloys and steel.
• Ni200/Ni201 purity — ≥99.2%/≥99.0% Ni with resistivity of 0.096 μΩ·m (20 °C).
• Hot-sale gauges — 0.15/0.2 mm within the 0.05-0.5 mm range.
• Custom widths and patterns — per drawing.
• Documented supply — EN 10204 3.1 MTC, ISO 9001 certified; 3-7 days small lots, 7-15 days standard.

Packs share space with BMS sensors, current-sensing electronics and communication components. Strip with lower magnetic permeability produces less field interaction near those components, which is why magnetic behaviour is a specification on electronics-aware pack designs.

Pure nickel is ferromagnetic below its Curie temperature of 358 °C, and its permeability is low relative to nickel-iron alloys and electrical steel. The magnetic behaviour of the strip follows the grade and condition; applications above 358 °C see paramagnetic behaviour.

Magnetic properties matter only if the rest of the strip is right: thickness tolerance, surface condition and low resistivity (0.096 μΩ·m) keep weld quality and current performance consistent while the magnetic specification is met.

The bands above are indicative for standard strip sizes. Strip with custom patterns is 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/N02201 before rolling, then every batch is gauged for thickness, 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; magnetic and corrosion behaviour 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.

Batteries and their electronics share the same housing, and magnetically quiet strip helps them work together. 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 battery strip in Ni200/Ni201 with per-batch composition analysis and EN 10204 3.1 mill test certificates on every shipment.

Packs share space with BMS sensors and current-sensing electronics; strip with lower permeability reduces field interaction near those components.

Pure nickel is ferromagnetic below its Curie temperature of 358 °C, and its permeability is low relative to nickel-iron alloys and electrical steel; above 358 °C it behaves paramagnetically.
