Pure nickel wire often gets reduced to a single number — 99.9% purity. That number matters, but it doesn't tell you what happens when your winding machine feeds 15,000 meters of 0.025 mm wire through a guide pulley at 600 rpm, or when the finished coil sits inside a turbine casing at 400°C for 8,000 hours. What matters then is whether the wire's face-centered cubic crystal structure stays stable under thermal cycling — and whether its ferromagnetic response remains predictable enough for your sensor circuit to read the same value at hour one and hour 8,000. DLX ships 0.025 mm nickel wire in four grades (N4, N6, Ni200, Ni201), hydrogen-annealed to a uniform bright finish, with the full melt traceability to back every spool.
| Grade | Ni Content | Key Differentiator | Best Structural Application | Reference Price (FOB, USD/kg) |
|---|---|---|---|---|
| N4 | Ni+Co ≥ 99.9% | Maximum purity; trace elements ≤ 0.1% total — no surprises in vacuum or inert atmosphere | Aerospace sensor leads, vacuum tube grids, semiconductor bonding wire | 62 – 72 |
| Ni201 | Ni ≥ 99.0% (C ≤ 0.02%) | Low carbon prevents grain-boundary carbide precipitation above 315°C | Gas turbine instrumentation, chemical plant thermowells, furnace windings | 48 – 56 |
| Ni200 | Ni ≥ 99.2% | Standard commercial grade; balanced formability and cost | General electrical contacts, battery tabs, solenoid windings | 42 – 50 |
| N6 | Ni+Co ≥ 99.5% | Cost-effective purity for industrial environments where 99.9% is over-specified | Resistance welding electrodes, electroplating anode leads, industrial sensor coils | 36 – 42 |
Prices FOB Shanghai, valid for 5–500 kg orders. Volume pricing for annual contracts. MOQ: 5 kg. Free sample of N6 or Ni200 up to 0.5 kg for first-time evaluation. Custom diameters, spool sizes, and cut lengths available.

Changzhou DLX Alloy Co., Ltd. controls every stage of nickel wire production under one roof: vacuum induction melting, hot forging, multi-pass cold drawing with in-line laser gauging, and continuous hydrogen atmosphere annealing. This vertical integration — rare among alloy wire suppliers — eliminates the quality gaps that appear when melting, drawing, and heat treatment are split across three different subcontractors. Our 12,000 m² Changzhou facility runs five dedicated wire drawing lines and two hydrogen annealing furnaces, producing 1,200 metric tons of nickel alloy wire annually. ISO9001 certified since establishment in 2002, SGS audited, serving precision manufacturers across 40+ countries. When your design specifies 99.9% nickel with a defined magnetic response and a guaranteed continuous length, we deliver exactly that — with the melt-to-spool paperwork to prove it.
Three properties combine in nickel that no single alternative metal offers: (1) an FCC crystal structure that remains ductile from cryogenic to over 1000°C — no brittle transition; (2) ferromagnetic response that is stable and repeatable across thermal cycles — critical for sensors and actuators; (3) intrinsic corrosion resistance that doesn't depend on a coating or plating layer that can crack, peel, or wear through. Copper corrodes. Steel rusts. Nickel stays nickel.
If your wire operates above 315°C, select Ni201. Its carbon content is capped at ≤ 0.02% — low enough to prevent chromium carbide precipitation at grain boundaries, which is the primary failure mechanism for standard Ni200 in sustained elevated-temperature service. Below 315°C, Ni200 offers the same corrosion resistance at a lower cost. For vacuum or inert-atmosphere applications where any trace outgassing is unacceptable, N4 (Ni+Co ≥ 99.9%) is the correct choice.
Yes. Our multi-pass drawing process produces 0.025 mm wire in continuous, weld-free strands. A standard DIN 100 spool holds over 15,000 meters of unbroken wire. For longer requirements, DIN 200 and DIN 300 spool formats are available. Specify your minimum continuous length at inquiry — we will confirm feasibility against your requested spool format.
If you are winding a solenoid, a reluctance sensor, or a magnetic actuator, the wire's ferromagnetic response is not a secondary property — it is the primary functional requirement. Trace iron contamination from a mixed-alloy factory can shift coercivity and saturation unpredictably. DLX tests magnetic response on sample spools from every production batch using a vibrating sample magnetometer (VSM). Because we run a nickel-only facility, there is no iron cross-contamination to degrade that response over time.
Free samples of N6 and Ni200 grades up to 0.5 kg are available for first-time evaluation, shipped within 3 working days via DHL Express. N4 and Ni201 samples carry a nominal charge, fully refundable against your first production order of 50 kg or more. MOQ for production orders is 5 kg. Custom diameters outside the 0.025–10 mm standard range are available with a one-time tooling setup.
