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
Tensile Strength	403 MPa (58,500 psi)
Yield Strength (0.2% offset)	148 MPa (21,500 psi)
Elongation	40% min
Hardness (Rockwell B)	60 HRB
Density	8.89 g/cm³
Melting Point	1435–1445 °C

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.

💡 Key Advantages

Exceptional Purity – The catalogue lists ≥99.6% nickel; specify the analysis basis and required impurity limits for the order.
Corrosion Resistance – Select against the actual acid, alkali or marine medium, concentration, temperature and contaminants.
High Thermal Stability – Review oxidation, atmosphere, temperature and exposure duration for the intended thermal service.
Excellent Formability – Confirm bending, drawing or welding requirements, final condition and finished-part acceptance.
Low Carbon Content – Nickel 201 is selected for its reduced carbon content; evaluate graphitization risk for the specified service temperature and duration.
Electrical Conductivity – Specify electrical or thermal performance requirements for the wire size and component design.

✈ Applications

Possible uses of industrial nickel wire include the following component types. Confirm material grade, condition and application requirements for each order.

Electronics – Battery leads, connectors and resistance elements, subject to the required geometry and electrical performance.
Chemical Processing – Components for acid or caustic service after review of concentration, temperature and impurities.
Aerospace & Marine – Components selected against the project specification, environment and required qualification.
Heat Treatment – Furnace, sensor or heating components selected for the operating atmosphere, temperature, load and duration.
Scientific Equipment – Instrument parts selected for the drawing, cleanliness and material-document requirements.
Medical Applications – Device or diagnostic components require the specified material, cleanliness, manufacturing process and intended-use validation. Confirm these requirements with the device manufacturer.

📏 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

🌍 Standards & Equivalents

ASTM B160 – Nickel Rod and Bar; this is a rod/bar reference. State the required wire specification and edition in the inquiry.
UNS N02201 – Nickel 201 material designation; confirm grade chemistry and wire acceptance requirements for the order.
W.Nr. 2.4068 – Material designation reference; confirm the required grade, product form and specification before ordering.
JIS NW 2201 – Existing designation reference; confirm the required material designation, product form and specification before ordering.

For substitution across designation systems, compare the actual grade chemistry, product form, material condition and ordered acceptance requirements. Include the relevant wire specification and edition in the quotation request.

🛠 Fabrication & Processing

For nickel 201 wire, specify the intended GTAW/GMAW welding, cold working or annealing operation. Confirm the process procedure and required final properties for the wire diameter and finished component.

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.
