Nickel 200 (UNS N02200) round bar and rod, wrought and annealed to ASTM B160, with the composition and mechanical results of each heat recorded on a mill test certificate. Standard diameters 8-20 mm from stock, other sizes to drawing. Electrolytic nickel is feedstock, not this product.
Nickel 200 (UNS N02200) round bar and rod is a documented material: a fixed ASTM identity and a certificate that records what each lot contains. Commercially pure wrought nickel, Ni200 resists caustic alkalis and reducing media while holding the strength and ductility that machined components need. Standard diameters of 8 mm, 10 mm, 12 mm and 20 mm are produced annealed on the Changzhou line, with other sizes made to drawing, and a mill test certificate (EN 10204 3.1) issued for every lot. The grade sits in the pure nickel series, alongside the low-carbon and the high-purity members of the family.
Nickel materials are easy to confuse at the purchasing stage. Electrolytic nickel is a primary feedstock in cathode or plate form, produced by electro-refining. The bar form is wrought material, melted, cast and worked to size, then certified to ASTM B160. Within the wrought family, Ni200 and Ni201 differ only in carbon, while nickel alloy bars such as Monel and Inconel carry intentional alloy additions for duties outside pure nickel's range. A drawing that calls for Ni200 or UNS N02200 is answered by the wrought, certified bar, and where a process needs the grade in wire form, it is drawn as pure nickel wire.

One documented identity: UNS N02200 to ASTM B160.
Composition and mechanical results recorded for each heat.
Annealed bar in the four standard diameters; other sizes to drawing.
Produced under ISO 9001 and SGS systems since 2002.
The label repeats the heat number shown on the certificate.
UNS N02200 is the registered identity of Nickel 200, and ASTM B160 is the standard that sets its composition limits, mechanical minimums and test basis. Buying to the designation means the mill, the inspector and the end user read from one published basis, so a lot can be checked on receipt against numbers that were fixed before the order was placed. A description such as soft nickel or commercially pure nickel carries no such basis, and an enquiry that names only the description is quoted once the grade is pinned down.
The certificate that travels with a lot is issued against the standard, and its structure follows the standard: grade and heat number, then chemical analysis and mechanical results for that heat. A buyer checks two things, that the composition figures fall inside the standard's limits and that the heat number on the certificate matches the one on the bundle label. Values reported for a different heat, or a certificate issued against a different standard, are the two defects worth catching at goods-in.
On receipt the paperwork covers the material, and the bar itself is checked against the drawing for diameter and surface. Where a lot is being qualified for a new process, those checks are what tie the material to one melt and to one set of test results. A mismatch between label and certificate is settled from the lot records, and the earlier it is raised the less it costs, because the replacement bar can be scheduled with the next melt.
A drawing may call the grade by UNS number or by a national designation, and both describe one bar. Ni200 and Ni201 are covered by ASTM B160 (Nickel Rod and Bar), and the N4 and N6 purity grades sit under GB/T 4435 (Nickel and Nickel Alloy Bars), with export documentation running to EN 10204 3.1 whatever the callout. Where an incoming inspection works to a national standard, the counterpart is named on the offer so the two documents line up.
| Element | Ni200 (UNS N02200) | Ni201 (UNS N02201, for reference) |
|---|---|---|
| Ni+Co (min) | 99.2% | 99.0% |
| C (max) | 0.15% | 0.02% |
| Cu (max) | 0.25% | 0.25% |
| Fe (max) | 0.40% | 0.40% |

Ni201 is shown for selection reference only, and is available where the service calls for the lower carbon level.
Annealed bar: tensile strength ≥462 MPa, 0.2% yield strength ≥148 MPa, elongation ≥35%, hardness 90-120 HB. Physical constants: density 8.908 g/cm³, melting point 1435-1446°C, electrical resistivity 0.096 μΩ·m, thermal conductivity (Ni200) 70.2 W/m·K, ferromagnetic below the Curie point of 358°C.
Composition is taken from the heat analysis and the finished bar is gauged before packing. The mill test certificate (EN 10204 3.1) carries both sets of results for the heat, and the records stay with the lot number after shipment.
