Industrial pure nickel wire in 0.025 mm to 10 mm diameters, Ni200, Ni201, N4 and N6 grades with purity from ≥99.0% to ≥99.9%. Micro wire from 1 kg, standard from 5 kg, with EN 10204 3.1 mill certificates on export orders.
Industrial pure nickel wire is specified by medium first and grade second, because the two variables that decide service life are the corrosion profile and the operating temperature. Drawn from 0.025 mm to 10 mm in Ni200 (UNS N02200), Ni201 (UNS N02201), N4 (NP1) and N6 (NP2), the wire carries purity from ≥99.0% to ≥99.9% with carbon limits set per grade. Micro wire is ordered from 1 kg and standard wire from 5 kg, and each shipment can carry EN 10204 3.1 mill certificates for incoming inspection.
In chemical service, stainless steel wire relies on a passive oxide film that breaks down in reducing media, while nickel-plated wire depends on the integrity of its plating layer. Solid pure nickel wire carries no film and no plating: its corrosion resistance is a property of the metal itself, so cut ends, edges and weld zones keep the same resistance as the as-drawn surface. That is why industrial nickel wire keeps appearing in pumps, valves and heat exchangers where coated or filmed materials fail at the cut.

Corrosion resistance inherent to the metal: no film and no plating layer to wear away at a cut end or a weld zone.
Purity matched to grade: N4 at ≥99.9% Ni+Co down to Ni200 and Ni201 at ≥99.0–99.2%, with carbon limits per grade.
Melting point of 1435–1446°C for elevated-temperature service in aerospace and power generation.
Ductility and toughness: multiple slip systems let the wire draw, bend and weld without cracking.
Order terms: MOQ from 1 kg for micro wire, settled by L/C or T/T.
Multiple slip systems in the nickel lattice let the metal deform plastically instead of cracking, so the wire draws, bends and welds consistently, and components made from it survive vibration and thermal cycling. The same crystal structure sets the magnetic response, with the wire ferromagnetic up to a Curie point of 358°C wherever it sits near sensors or magnetic circuits. Annealed wire holds tensile strength of ≥462 MPa with elongation of ≥35%, which is the margin that matters on forming lines.
The wire appears in aerospace components for its oxidation resistance at elevated temperature, in power generation for heat and corrosion stability, and in chemical processing equipment for resistance to corrosive media. In each case the corrosion profile is set by the metal itself, so cut ends and weld zones behave like the as-drawn surface. For specific media, operating temperature and concentration are confirmed against the process conditions, and the mill certificate records the actual lot composition.
Purity is grade-dependent and not a single figure: N4 (≥99.9% Ni+Co) is the highest-purity designation, followed by N6 (≥99.5%), Ni201 (≥99.0%, C ≤0.02%) and Ni200 (≥99.2%, C ≤0.15%), and all four sit in the Pure Nickel Series. Specify the grade against the duty: research and vacuum service take N4, general industrial use takes N6, low-carbon welding-sensitive joints take Ni201, and standard mechanical and electrical duty takes Ni200. Applying 99.9% across the board over-specifies the price as well as the purity.
For chemical pumps, valves and heat exchangers, N6 or Ni200 balance corrosion resistance with cost. For aerospace and power generation service, N4 or N6 take the elevated-temperature duty. For electronic components and weld-sensitive assemblies, Ni201 or N4 protect joint quality where low carbon and high purity matter. Confirm grade, diameter, temper and quantity against your drawing, and the mill certificate records the actual lot composition of every spool.
