Ultra Thin 0.025mm Pure Nickel Wire with 99% Ni Purity and High Temperature

Our pure nickel wire offers excellent mechanical strength, corrosion resistance, and heat resistance. Ideal for various industrial applications including electrical apparatus and components, chemical machinery and processing equipment, rechargeable battery manufacturing, and electronics such as computers, cellular phones and power tools. Diameters run from 0.025mm ultra-thin wire to 10mm, in soft, hard and 1/2 hard tempers, with series options covering nickel 200 and nickel 201 wire. Documented purity follows the grade ladder from N4 (≥99.9%) down, resistivity is 0.096 μΩ·m at 20°C, and every spool carries EN 10204 3.1 MTC with heat traceability.

• Excellent mechanical strength, corrosion resistance and heat resistance.
• Ultra-thin options from 0.025mm — precise diameters for fine components.
• Multiple tempers — soft, hard and 1/2 hard for forming and service needs.
• Documented purity per grade — N4 ≥99.9% down to Ni200 ≥99.2%.
• Low resistivity among nickel materials — 0.096 μΩ·m at 20°C.

Our pure nickel wire is ideal for various industrial applications including: electrical apparatus and components; chemical machinery and processing equipment; rechargeable battery manufacturing; and electronics — computers, cellular phones and power tools.

Diameter defines the wire: catalog range covers 0.025-10mm, with ultra-thin options from 0.025mm for fine components and heavier wire for industrial service. Tolerances are confirmed per drawing, and diameter consistency is inspected along the length of every spool.

Wire is supplied in soft, hard and 1/2 hard tempers to match the application — soft for forming and shaping, harder tempers for service strength. The annealed baseline is documented per heat: ≥462 MPa tensile strength, ≥35% elongation and 90-120 HB hardness.

Pure nickel wire holds its properties under heat: melting point of 1435-1446°C and Curie temperature of 358°C, with resistivity of 0.096 μΩ·m at 20°C and thermal conductivity of 70.2 W/m·K for Ni200 — the combination electrical and high-temperature applications depend on.

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

The 1 kg minimum applies to ultra-thin wire (≤0.05mm); standard wire grades are available at 5 kg MOQ per the grade-based schedule.

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

• Incoming: raw nickel verified per heat before processing.
• In-process: diameter checked along the length with calibrated instruments; surface inspected.
• Final: chemistry verified per heat; tensile and hardness sampled per heat.
• Documentation: EN 10204 3.1 MTC with heat number, test results and full traceability.

Ni200/Ni201 wire is manufactured and tested to ASTM B164; N4/N6 follow GB/T 21653. Testing methods and acceptance criteria follow the drawing specification and applicable standards.

Wire is supplied on spools packed in carton boxes, or in coils with polybag protection, keeping the surface clean 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.

Thin wire is where a supplier's process discipline shows: at 0.025mm, a fraction of a micron of diameter variation changes resistance per metre. Changzhou DLX Alloy Co., Ltd. produces pure nickel wire across the full 0.025-10mm diameter range, with soft, hard and 1/2 hard tempers, on a nickel-only 12,000 m² line that has been refining nickel alloys since 2002. From fine wire for electronics to heavier wire for chemical processing, the diameter, temper and traceability are controlled and documented the same way — per heat, per spool, per EN 10204 3.1 MTC.

Ultra-thin options start at 0.025mm; the catalog diameter range is 0.025-10mm with tolerances confirmed per drawing.

Documented per grade: N4 (NP1) ≥99.9%, N6 (NP2) ≥99.5%, Ni201 ≥99.0% and Ni200 ≥99.2% per the respective GB and ASTM systems.

Soft, hard and 1/2 hard — soft for forming and shaping, harder tempers for service strength.

1 kg for ultra-thin wire (≤0.05mm); standard wire grades are available at 5 kg MOQ 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. Wire meets ASTM B164 (Ni200/Ni201) and GB/T 21653 (N4/N6).
