This 0.025mm high purity nickel wire is built for industrial applications — 99.9% minimum nickel content (N4/NP1), corrosion resistant, precision-drawn micro wire. The purity claim is grade-accurate: N4 holds Ni+Co of 99.9% or higher, tested per batch. Produced on our own nickel-alloy line, every spool is inspected per batch before packaging.
| Parameter | Value | Note |
|---|---|---|
| Diameter | 0.025 mm (micro wire) | 0.025-10 mm range available |
| Tolerance | Per drawing / GB/T 21653 | exact values per drawing |
| Continuous length | Per order | dependent on diameter |
| Temper | Soft / hard / 1/2 hard | per drawing |
| Surface | Clean, oxide-free | per drawing |
MOQ: 1 kg for micro wire (≤0.05 mm). Ordering information — grade, diameter, temper, quantity, standard and destination port — confirmed at quotation.
N4 (NP1) holds Ni+Co of 99.9% or higher, keeping the total impurity budget below 0.1% — the basis of consistent corrosion behaviour and stable conductivity in demanding service. It is positioned for vacuum electronics and high-purity applications.
High purity reduces the impurity sites where corrosion starts. The wire is dependable in caustic alkalis and chloride-bearing media, and its behaviour is confirmed against the specific service conditions rather than claimed beyond the material's established performance.
At 0.025 mm, drawing precision decides performance. Wire is drawn to the specified diameter with tolerances locked per drawing and inspected at final inspection, so the micro wire holds its dimension and surface across the spool.
Produced on our own nickel-alloy line, every spool passes chemical composition analysis, diameter inspection and surface checks in our in-house inspection process before packaging.
Typical use: vacuum electronics, chemical and electronic components, and high-purity industrial assemblies. Diameter, temper and finish are confirmed against the application at order time.

Purity at 99.9% is a budget, not a slogan: every 0.1% of impurity is corrosion, resistance drift or weld inconsistency waiting to happen. Changzhou DLX Alloy Co., Ltd. — 12,000 m² nickel-only plant since 2002, 1,200 tonnes per year, ISO9001 with SGS support — draws 0.025mm N4 micro wire under that discipline: per-batch composition testing and diameter inspection in-house, with EN 10204 3.1 documentation on request.
A: Yes — N4 (NP1) holds Ni+Co of 99.9% or higher, tested per batch with EN 10204 3.1 documentation on request.
A: 0.025 mm micro wire is featured, with the 0.025-10 mm range available; MOQ 1 kg for micro wire.
