High Purity Nickel Electrode Wire 0.05-0.5mm – ASTM B164
Overview
Electrode wire is a consumable with no margin for guesswork — every coil has to feed, weld or braze the same way. Our nickel electrode wire in 0.05-0.5 mm diameters is drawn to tight tolerances with a bright, silver-colored finish, in high-purity grades up to N4 at ≥99.9% Ni+Co. Start with a free sample, confirm the grade on your line, then scale the order — with 5 kg MOQ (1 kg for ≤0.05 mm micro wire) and 7-15 day delivery from our ISO 9001 certified nickel-only line.
Dimensions & Tolerances
Nickel electrode wire is produced in diameters of 0.05-0.5 mm, with the full catalog wire range of 0.025-10 mm available on request. Diameter tolerance, spool size and coil weight are confirmed against the drawing before production and locked in the batch record.
Key Strengths
- High purity option — N4 at ≥99.9% Ni+Co for sensitive electrode and welding service.
- Tight diameter tolerance — 0.05-0.5 mm drawn to tolerance per drawing.
- Bright, clean surface — silver-colored finish for consistent feeding and stable contact.
- Low MOQ, sample first — 5 kg standard (1 kg for ≤0.05 mm); N6/Ni200 free samples of 0.5 kg.
- Documented supply — ISO 9001 certified line, EN 10204 3.1 MTC per shipment, 7-15 day delivery.
Technical Deep Dive
Electrode Service & Material Requirements
Nickel electrode wire serves as core wire for welding electrodes and resistance welding service, where consistent chemistry and clean surface determine joint quality. Grade purity and diameter tolerance are matched to the electrode process and confirmed against the drawing.
Purity & Conductivity
High-purity N4 (≥99.9% Ni+Co) minimizes impurity effects on weld behaviour, while low electrical resistivity of 0.096 μΩ·m (20 °C) supports stable current transfer in resistance welding service.
Diameter Tolerance & Surface
Wire is cold drawn to the specified diameter with a bright, silver-colored finish, free of scale and surface defects. Diameter tolerance and surface condition are gauged per batch and confirmed before production.

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 coil 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
Packaging & Delivery
Wire is supplied on spools, coils or pay-off packs as specified, protected against moisture and packed in cartons and export cases. Documentation — mill test certificates, batch records and packing lists — accompanies every order, with a standard lead time of 7-15 days from confirmed drawing.
About DLX Alloy
Electrode wire is ordered in small coils and judged coil by coil, which is why DLX Alloy runs every order — small or large — through the same discipline. Since 2002 our nickel-only line has drawn wire across 12,000 m² of floor space with 1,200 t/yr rated capacity, ISO 9001 certified and SGS audited, with per-batch composition analysis and EN 10204 3.1 mill test certificates on every spool.
FAQ
Can I get a sample first?
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 is the MOQ?
5 kg for standard wire; 1 kg for ≤0.05 mm micro wire.
What diameters are available?
0.05-0.5 mm as listed, with the full catalog range of 0.025-10 mm available on request.
Which grade should we use for electrode wire?
N4 (≥99.9% Ni+Co) for high-purity electrode service; Ni200/Ni201 and N6 cover broader welding and brazing applications.
What is the delivery time and documentation?
7-15 days from confirmed drawing; EN 10204 3.1 mill test certificates, batch records, ISO 9001/SGS certificates and packing list.
