ISO 9001 & SGS Certified • Samples Available • 3-7 Day In StockNickel's chemistry is fixed at atomic mass 58.6934 g/mol — and what a wire maker does with that metal decides whether it performs or fails in your application. This high performance nickel wire, drawn from 0.025 mm to 10 mm in grades 200, 201, N4 and N6, is built for superior corrosion resistance: a dense oxide film that blocks oxidation, stability in alkaline and reducing media, and predictable mechanical and electrical behaviour coil after coil. It is ferromagnetic with a face-centered cubic crystal structure, and it is one of the easiest wires to trial — the N6 sample is free and micro wire starts at a 1 kg MOQ.

Solid Pure Nickel vs. Plated Wire vs. Heating Alloy: Three Different Products
"Nickel wire" covers three different products, and they are not interchangeable. This page supplies solid pure nickel wire — every atom through the section is nickel, which is why the atomic mass, crystal structure and magnetic properties are stated: solid nickel gives through-thickness chemistry, weld consistency and predictable corrosion behaviour. Nickel-plated steel wire is a steel core with a nickel coating; it costs less but fails where through-thickness corrosion or weld penetration matters. Nickel-chromium heating alloy wire is a high-resistance material for heating elements, a separate product line. If your drawing specifies pure nickel wire — as a conductor, a corrosion-resistant lead, or a structural wire — this is the specification.

Technical Details
What "High Performance" Means in Nickel Wire
High performance is not a slogan; it is measurable. Purity is graded (Ni200 ≥99.2%, Ni201 ≥99.0%, N6 ≥99.5%, N4 ≥99.9% Ni+Co); corrosion resistance comes from a dense protective oxide film that forms in air and blocks further attack; and consistency comes from batch-level inspection of chemistry, diameter, surface and mechanical properties. The metal's structure — face-centered cubic, ferromagnetic with a Curie temperature of 358°C — is stable and predictable, which is what makes it a trusted material in aerospace, gas turbines and high-temperature alloy production.
Corrosion Profile: Where Superior Resistance Holds
Pure nickel wire resists oxidation and water vapour at high temperature, holds against alkaline media (sodium hydroxide, potassium hydroxide, ammonia) and reducing chloride environments, and performs in seawater service. The boundary: strong oxidizing acids such as nitric acid and hot concentrated sulfuric or hydrochloric acid will attack nickel — evaluate the actual medium, concentration and temperature before specifying. Corrosion resistance remains stable across temperature and pressure conditions, supporting long service in chemical, petrochemical and marine environments.
Grade Selection: 200 201 N4 N6
Ni201 (C ≤0.02%) is the low-carbon choice for wire that runs hot; Ni200 (≥99.2%) is the economical standard; N4 (≥99.9%) is specified where maximum purity matters; N6 (≥99.5%) covers general duty at the lowest cost. All four are commercial-purity nickel, not alloys — the grade decision is purity, carbon and cost, and the mill certificate states the actual batch chemistry.
A Sample-First Path for New Suppliers
Before committing to production quantity, verify the wire in your own line: request the free N6 sample (0.5 kg), run your corrosion or weld test, and confirm the chemistry against the mill certificate. Production follows at 1 kg MOQ for micro wire or 5 kg for standard sizes, with the same batch-level inspection — composition, dimensions, mechanical properties and surface — applied to your order as to the sample.

Quality Assurance
Every batch passes chemical composition analysis, dimensional measurement, mechanical property testing and surface inspection before release, and batch records accompany the shipment. For corrosion service, surface condition matters — oxides and contaminants are the first failure points — so surface inspection is performed per spool on micro sizes. Export orders ship with EN 10204 3.1 mill test certificates.
