Ni200
Nickel 200 Wire
Commercially pure nickel with a carbon ceiling of 0.15 %. It is the default choice for lead wire, electrodes and current collectors, where low resisti…

Pure Nickel Wire
Two grades, one drawing floor. Carbon is the only number that matters — 0.15 % for Ni200, 0.02 % for Ni201 — and it decides whether the wire survives above 315 °C.

| Grade | GB | UNS | Carbon | Max service in air |
|---|---|---|---|---|
| Nickel 200 | N6 | N02200 | ≤ 0.15 % | ≈ 315 °C |
| Nickel 201 | N4 | N02201 | ≤ 0.02 % | ≈ 600 °C |
Both grades are commercially pure nickel with the same resistivity and the same density. The difference is carbon, and the difference only shows up at temperature: above roughly 315 °C, carbon in Nickel 200 graphitises at the grain boundaries and the wire embrittles. Below that, Nickel 200 is the cheaper correct answer.
What it is used for
- Lead wire for heating elements and resistors
- Electrodes, nickel mesh and woven cloth
- Battery current collectors and tabs
- Vacuum, electron and semiconductor devices

Why fine nickel is not a commodity
Nickel work-hardens quickly. Drawing to 0.025 mm means many passes with an anneal in between, and the diameter has to land on every pass — not only at the end. Four of our six drawing lines are fine-wire lines for exactly this reason.

Ni201
Nickel 201 Wire
The low-carbon version of Nickel 200. Holding carbon at 0.02 % stops graphitisation above roughly 315 °C, which is where Nickel 200 starts to embrittl…
Questions we get asked
Do you supply 0.018 mm nickel wire?
0.025 mm is the routine minimum for pure nickel. Finer diameters are drawn on request — ask with the length and spool weight you need.
Is a material test certificate included?
Yes, as standard: chemistry and mechanical properties per lot, with the carbon figure stated explicitly.
Send the specification — diameter, grade, temper, quantity.
We come back with a confirmed lead time and the documentation we can issue for the shipment. 100 g sample at cost; orders from 1 kg.
