Overview
Micro wire is drawn to macro standards: 0.025 mm industrial grade nickel wire has to spool, feed and weld without surprises, batch after batch. Produced from Ni200/Ni201 pure nickel (≥99.2%/≥99.0% Ni) with N4 and N6 grades available, our micro wire is drawn to tolerance and verified per batch on our own nickel-only line — 1 kg MOQ, N6/Ni200 free samples of 0.5 kg, and 3-7 day delivery for small lots, 7-15 days for standard production.
Dimensions & Tolerances
Wire is produced at 0.025 mm as specified, within the catalog wire range of 0.025-10 mm. Diameter tolerance, spool size and coil weight are confirmed against the drawing before production and locked in the batch record.
Key Strengths
- Industrial-grade consistency — 0.025 mm drawn to tolerance, verified per batch.
- High-purity grades — Ni200 ≥99.2% / Ni201 ≥99.0% / N4 ≥99.9% Ni+Co.
- Micro wire on spools — clean, continuous lengths for feeding and weaving.
- Low MOQ, sample first — 1 kg micro-wire MOQ; N6/Ni200 free samples of 0.5 kg.
- Documented supply — EN 10204 3.1 MTC, ISO 9001 & SGS audited, 7-15 day delivery.
Technical Deep Dive
Drawing 0.025 mm to Industrial Tolerances
At 0.025 mm, drawing is a tolerance game: the wire is reduced through multiple passes with per-batch diameter gauging, so the finished micro wire feeds, weaves or reinforces without interruption.
Purity and the Grade Spectrum
Industrial service spans a purity spectrum: Ni200 (≥99.2% Ni) for general service, Ni201 (≥99.0% Ni, ≤0.02% C) for low-carbon stability, N6 (≥99.5% Ni+Co) for industrial corrosion, and N4 (≥99.9% Ni+Co) for the most demanding applications.
Batch Consistency at Micro Scale
At micro scale, batch consistency is everything: a single diameter drift changes resistance and feeding behaviour. Composition is analysed and diameter is gauged per batch, with batch records tied back to the melt.

Quality Assurance
Quality control starts at the melt: raw material composition is verified against the grade specification before drawing, then every batch is gauged for diameter, surface and spool condition, and checked for continuity. Batch records link each order back to the melt, and EN 10204 3.1 mill test certificates ship with every consignment.
Applicable Standards
- ASTM B164 — nickel and nickel alloy rod, bar and wire
- GB/T 21653-2008 — nickel and nickel alloy wire
- EN 10204 3.1 mill test certificates accompany shipments
References
Material data on this page follows ASTM B164 and GB/T 21653-2008; 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.
Packaging & Delivery
Micro wire is supplied on spools, protected against moisture and kinking, packed in cartons and export 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.
About DLX Alloy
Micro wire and 10,000-tonne capacity belong on the same line — the discipline that draws 0.025 mm is the same one behind every shipment. DLX Alloy has run a nickel-only line since 2002 across 12,000 m² of floor space, ISO 9001 certified and SGS audited, drawing and inspecting micro wire per batch with EN 10204 3.1 mill test certificates on every spool.

FAQ
How is 0.025 mm wire drawn and verified?
The wire is reduced through multiple drawing passes, then gauged for diameter per batch; tolerance is confirmed against the drawing and locked in the batch record.
Which grades are available for industrial service?
Ni200 (≥99.2% Ni), Ni201 (≥99.0% Ni, low carbon), N6 (≥99.5% Ni+Co) and N4 (≥99.9% Ni+Co); selection is confirmed against the application.
What is the MOQ for micro wire?
1 kg for wire ≤0.05 mm; sample and trial quantities can be discussed per request.

Yes. N6/Ni200 samples of 0.5 kg are free; N4/Ni201 samples are charged and refunded on a first order of 50 kg or more.
What documentation ships with orders?
EN 10204 3.1 mill test certificates, batch composition and dimensional records, ISO 9001/SGS certificates and packing list.
