Description
Nickel 201 Wire – Coil and Straight Wire
📖 Product Overview
The nickel 201 wire is listed here as commercially pure, low-carbon nickel in coil, spool or cut-length form. The catalogue chemistry shows at least 99.6% nickel; confirm the ordered grade, analysis basis and batch limits when requesting a quotation. Select diameter, tolerance, material condition and surface for the intended component.
Request a Nickel 201 wire quotation: send wire diameter and tolerance, coil or straight length, quantity, final condition, surface requirements and intended service. Include the required wire specification, inspection scope and batch documents. Explore nickel wire or send your drawing and order requirements.
For this high purity nickel wire, confirm the drawing, bending or welding process and required final condition. The catalogue carbon limit is <0.02%; Nickel 201 is the low-carbon version of Nickel 200, used where resistance to graphitization during elevated-temperature exposure matters. Temperature, atmosphere, load and duration remain part of material selection.
For electrical connections, thermal components or chemical equipment, select the pure nickel wire against the component drawing, operating environment and acceptance criteria. Confirm the required wire properties and lot documentation with the quotation.
🧪 Chemical Composition (Nickel 201 / UNS N02201 — Catalogue Reference)
The following catalogue limits are buying references. Confirm the ordered wire specification, whether nickel is reported alone or with cobalt, impurity limits and batch analysis before acceptance.
| Element | Content (%) |
|---|---|
| Nickel (Ni) | ≥ 99.6 |
| Carbon (C) | ≤ 0.02 |
| Copper (Cu) | ≤ 0.25 |
| Iron (Fe) | ≤ 0.40 |
| Manganese (Mn) | ≤ 0.35 |
| Silicon (Si) | ≤ 0.35 |
| Sulfur (S) | ≤ 0.01 |
Low carbon is a characteristic of this nickel wire. Review chemical-service suitability using medium composition, concentration, temperature, impurities and exposure conditions; the chemistry table alone does not establish corrosion performance for a component.
⚙ Mechanical Properties (Annealed Condition)
| Property | Value |
|---|---|

Use the annealed catalogue values when discussing this corrosion resistant nickel wire, then confirm the supplied condition, test direction and required mechanical acceptance for the ordered diameter. Finished-component design and service conditions determine suitability.
🔥 Heat Resistance
For heat resistant nickel wire applications considering service above the catalogue 600°C reference, provide temperature, atmosphere, load, exposure time and thermal cycling. Review Nickel 201 selection and the required final condition with the application engineer before ordering.

📏 Size Range & Specifications
Specify surface finish and bulk material condition separately: bright describes a surface, while annealed describes material condition. Confirm their required combination, diameter tolerance and coil or straight-length format in the quotation.
Our pure nickel wire is available in diameters from 0.1 mm to 5 mm, with custom diameters on request. It is supplied in coils, spools, or cut lengths according to customer requirements.
| Diameter Range | Tolerance | Surface or Material Condition |
|---|---|---|
| 0.10 – 0.50 mm | ±0.005 mm | Bright / Annealed |
| 0.50 – 2.00 mm | ±0.01 mm | Bright / Annealed |
| 2.00 – 5.00 mm | ±0.02 mm | Bright / Annealed |

Nickel 201 Wire Procurement FAQ
Does ASTM B160 cover this wire?
ASTM B160 covers nickel rod and bar. For wire, state the required product-form specification, grade and edition so acceptance requirements can be confirmed.
What should I send for a coil or cut-length quote?
Provide diameter and tolerance, quantity, coil/spool format or straight length, material condition, surface and required inspection documents.
How should Nickel 200 and Nickel 201 be selected?
Nickel 201 is the low-carbon version. Select using temperature, atmosphere, load, exposure time and chemical-service conditions, then confirm grade and batch requirements.
For flat-product inquiries, review Nickel 201 plate and the B162 plate order reference. For tubular components, see Ni200 seamless tube or browse nickel materials.
