Electronic assemblies put a conductor into small spaces, and what they need from it is resistance that does not drift from coil to coil. This pure nickel wire is drawn from 0.025 mm to 10 mm and holds electrical resistivity of 0.096 μΩ·m, with the corrosion resistance and weldability that plated substitutes do not offer. Four commercial-purity grades (Ni200, Ni201, N4, N6) span the purity and cost levels, and each coil ships with batch records for incoming inspection.
Copper has lower resistivity than nickel and takes the high-current bus bars where raw conductivity is the only criterion. Nickel is specified where the conductor has to hold its resistance in a corrosive atmosphere, weld to other nickel components, or survive temperature cycling inside a sealed assembly. Its oxide layer stays thin and adherent in normal atmospheres, while copper oxide grows with time, and that growth is what raises contact resistance in service. Within electronic industrial assemblies, the parts that come to nickel wire are leads and connectors.

| Wire (round) | 0.025–10 mm | Soft / Hard / 1/2 Hard |
Micro wire (≤0.05 mm) is available at a 1 kg MOQ; standard wire sizes start at a 5 kg MOQ. Thickness and dimensions can be produced to customer requirements; submit the drawing for confirmation.
Conductivity: electrical resistivity of 0.096 μΩ·m keeps resistance low and stable in current-carrying components.
Surface behaviour: the oxide layer on nickel stays thin in normal atmospheres, so contact resistance does not climb over the life of an assembly.
Joining: welds cleanly to itself and to other nickel parts, and takes solder for lead termination.
Grade options: Ni200, Ni201, N4 and N6 cover the purity and cost levels for electronic service.
Micro capability: drawn to 0.025 mm for instrument and sensor leads, checked spool by spool.
Electrical resistivity of 0.096 μΩ·m is the figure that matters for a lead, a connector or a shielding run. It stays put in service, because pure nickel carries no alloying elements to redistribute and the thin oxide layer that forms in normal atmospheres does not build the way copper oxide does. For the assembly that translates into a predictable voltage drop and low heat at the joint over the life of the assembly.
The wire covers micro sizes from 0.025 mm for instrument and sensor leads, fine gauges for winding and shielding, and heavier diameters up to 10 mm for larger connections. Soft temper suits bending and terminal forming, while hard or 1/2 hard holds shape in self-supporting leads. Stamped contacts and flat shielding formed from flat stock come from the pure nickel strip line, and custom diameters and tempers are set per drawing.
Ni201 (≥99.0% Ni, C ≤0.02%) is the usual electronics choice, because the low carbon supports long-term stability in soldered and heated assemblies. Ni200 (≥99.2%) is the economical standard, and N4 (≥99.9%) is specified where maximum purity is required. All four grades are commercial-purity nickel with a common conductivity figure, so the decision turns on purity and cost.
A scratch or a diameter drift changes contact resistance and weld behaviour on a wound lead, so gauge and surface are held to the drawing on every spool. The measurement window is narrowest at 0.025 mm, where each spool is checked against the drawing before it is closed and packed.

The test set for an electronic order covers composition by analysis, then dimension and surface condition, then mechanical properties, and the results are filed against the lot number printed on the spool label. Micro sizes are checked spool by spool rather than by lot alone. Export orders ship with EN 10204 3.1 mill test certificates.

Micro and fine wire is wound on spools and packed in carton boxes; larger diameters are supplied as coils in polybags or on spools as requested. Spools carry the gauge and the lot number for incoming inspection. Delivery is 7–15 days for standard production, 3–7 days for small in-stock quantities, and 15–30 days for complex custom work.
Electronic customers qualify a grade once and reorder against it, so the drawing, the chemistry and the process history of each qualified item stay on file at the mill. DZX was founded in 2002, holds ISO 9001 and SGS certification, and brings 20+ years of nickel drawing experience, 50+ patents, 1,000+ product configurations and 2,000+ partners across 60+ export countries.

Electrical resistivity is 0.096 μΩ·m, a stable conductor figure for leads, connectors and shielding. Resistance heating belongs to the nickel-chromium alloys, which are a separate product line.
Ni201 (≥99.0%, C ≤0.02%) is the usual choice where long-term stability matters in soldered and heated assemblies. Ni200 (≥99.2%) is the economical standard, and N4 (≥99.9%) is specified where maximum purity is required. Conductivity is common to all four grades, so purity and cost decide.
Down to 0.025 mm, held at the tight end of the tolerance band, with diameter and surface finish checked spool by spool. Tolerances for a given order are set per drawing.
Yes. Custom diameters and tempers are set per drawing, with cut lengths quoted on request. State the forming process (winding or terminal forming) and the temper is matched to it.
Micro wire (≤0.05 mm) starts at 1 kg; standard wire at 5 kg. Samples are free for N6/Ni200 (0.5 kg); N4/Ni201 samples are charged and refunded on a first order of 50 kg or more.
Standard production ships in 7–15 days; small in-stock quantities in 3–7 days; custom requirements in 15–30 days after the drawing is approved. Export orders include EN 10204 3.1 mill certificates and batch test records.
