Overview

India's battery, electronics and chemical processing industries are scaling fast, and importers there order pure nickel wire by grade, purity and export documentation. High purity nickel wire in Ni200, Ni201, N4 and N6 grades is drawn from 0.025 mm to 10 mm with a face-centered cubic structure, giving predictable forming, welding and corrosion behaviour. The grade matrix covers ≥99.0% to ≥99.9% nickel with carbon limits specified per grade, so the wire is matched to the application. Micro wire is available from 1 kg, standard wire from 5 kg, with EN 10204 3.1 mill certificates issued for customs clearance and buyer inspection.

Four Grades, One Material: The Pure Nickel Family

This page covers commercial pure nickel wire — Ni200 (UNS N02200), Ni201 (UNS N02201), N4 (NP1) and N6 (NP2). These are purity designations, not alloy grades: pure nickel carries no deliberate alloy additions, which is why the shorthand "200" and "201" should be written as Ni200 and Ni201 to avoid confusion with alloy numbering systems. The face-centered cubic lattice is shared by all four grades and is the reason forming, welding and magnetic behaviour stay consistent across the matrix.

Specifications

Diameters from 0.025 mm to 10 mm are drawn across our pure nickel wire range, with custom diameters and tolerances produced per drawing. Micro wire (≤0.05 mm) is ordered from 1 kg; standard wire from 5 kg.

Key Strengths

• All four grades on one wire program — Ni200, Ni201, N4 and N6 — with purity and carbon limits specified per grade.

• Face-centered cubic structure for uniform forming, bending and welding behaviour.

• Corrosion and oxidation resistance for chemical processing, aerospace and electronics service.

• Ferromagnetic behaviour (Curie point 358°C) for motors, transformers and magnetic components.

• Export documentation for Indian imports — EN 10204 3.1 mill certificates, batch records and packing lists.

Technical Details

How the FCC Lattice Shapes Wire Behaviour

Nickel crystallizes in a face-centered cubic (FCC) lattice, and the structure sets the wire's shop-floor behaviour: multiple slip systems allow uniform plastic deformation, so the wire bends, coils and forms without cracking, and weld joints stay consistent along the spool. The FCC lattice is also the basis of the ferromagnetic response that matters in motors, transformers and magnetic sensors — nickel is ferromagnetic up to its Curie point of 358°C.

Corrosion in Service: Media, Temperature and Grade

Pure nickel resists corrosion in reducing media, alkalis and many organic environments, and holds up to oxidation in moderate-temperature service — the combination that puts it in chemical processing equipment, aerospace components and battery assemblies. Resistance is inherent to the metal rather than to a surface treatment, so cut ends and weld zones keep the same profile as the as-drawn surface. Confirm the operating media, temperature and concentration against your process before ordering; the mill certificate records the actual lot composition.

Four Grades, One Wire: Ni200 vs Ni201 vs N4 vs N6

All four grades sit in the pure nickel series, and each is selected against the service media and price target. N4 (≥99.9% Ni+Co) serves the most demanding purity and research duties; N6 (≥99.5%) covers general industrial use; Ni201 (≥99.0%, C ≤0.02%) suits low-carbon, welding-sensitive applications; Ni200 (≥99.2%, C ≤0.15%) is the standard mechanical and electrical grade. Because purity, carbon limit and price move together, the grade is chosen against the application — not by habit.

Standards and Documentation for India Imports

Wire is supplied to ASTM B164 for Ni200/Ni201 and to GB/T 21653 for N4/N6, with export documentation per EN 10204 3.1 — the inspection document commonly requested for nickel imports into India. Each shipment can include the mill test certificate, batch records and packing list matched to the order, so the documentation for customs and incoming inspection arrives with the material rather than after it.

Pricing

Wire is priced by grade, FOB USD/kg: N4 $420-480, Ni201 $350-390, Ni200 $340-380, N6 $300-340. Micro wire (≤0.05 mm) from 1 kg; standard wire from 5 kg. Custom diameters and tight tolerances are quoted per drawing.
