High purity nickel wire in Ni200, Ni201, N4 and N6 grades, drawn from 0.025 mm to 10 mm for chemical, aerospace and electronics service. Ferromagnetic below 358°C, shipped to India with EN 10204 3.1 mill certificates. Micro wire from 1 kg, standard wire from 5 kg.
High purity nickel wire is ordered into India by grade and documentation, and both are settled before price is discussed. Four grades are drawn from 0.025 mm to 10 mm: Ni200 (UNS N02200, ≥99.2%), Ni201 (UNS N02201, ≥99.0%), N4 (NP1, ≥99.9% Ni+Co) and N6 (NP2, ≥99.5%), with carbon limits set per grade. Micro wire is ordered from 1 kg and standard wire from 5 kg, and EN 10204 3.1 mill certificates are issued for customs clearance and incoming inspection.
The four designations on this page are commercial-purity nickel, and they leave one production line. Ni200 and Ni201 follow the UNS system, while N4 and N6 follow the GB system, and NP1 and NP2 are the domestic shorthand for the same two materials. Writing the shorthand "200" and "201" as Ni200 and Ni201 keeps the purity designations separate from alloy numbering systems.

The four designations are purity designations rather than alloy grades, and the numbering runs on two systems. Ni200 and Ni201 are UNS designations for commercial-purity nickel; N4 and N6 are the GB equivalents, with NP1 and NP2 as the domestic shorthand for the same two materials. None of the four carries a deliberate alloying addition, so what separates them is nickel content and carbon limit, and the certificate states the system used on the order. That keeps one material identifiable when customs and the buyer's inspection department read different document sets.
Reducing media, alkalis and many organic environments sit inside the service range, and oxidizing acids sit outside it. Inside that range the grade follows the position: N4 where the highest purity is required, N6 for general industrial wire, Ni201 where low carbon protects weld quality, and Ni200 for standard mechanical and electrical service. Operating temperature and concentration are checked against the process before the grade is fixed.
All four designations sit in the Pure Nickel Series, and purity and carbon limit move together with price. N4 holds Ni+Co at ≥99.9% Ni+Co with carbon to 0.01%, N6 at ≥99.5% with carbon to 0.10%, Ni200 at ≥99.2% with carbon to 0.15% and Ni201 at ≥99.0% with carbon to 0.02%. The lowest-carbon designation is therefore not the highest-purity one, which is why welding-sensitive positions can specify Ni201 and pay less per kg for the property that decides the result.
Wire is supplied to ASTM B164 for Ni200 and Ni201 and to GB/T 21653 for N4 and N6, with export documentation to EN 10204 3.1, the inspection document that Indian importers request for nickel shipments. Each shipment can carry the mill test certificate, batch records and packing list matched to the order, so customs clearance and incoming inspection read one document set.
