UNS N02201 Nickel 201 Wire | Soft Annealed & Hard Drawn Pure Nickel Wire

Nickel 201 Wire (UNS N02201) is a commercially pure wrought nickel wire with low carbon content (≤0.02%), designed for applications requiring excellent corrosion resistance and superior thermal and electrical conductivity. As a low-carbon modification of Nickel 200, Nickel 201 is particularly suitable for high-temperature and high-pressure environments where minimizing graphitization and intergranular corrosion is critical.

With a purity level of ≥99.5% and outstanding formability, Nickel 201 wire is widely used in chemical processing, battery production, electrical heating elements, marine engineering, and precision electronics. The material offers non-magnetic properties, excellent resistance to caustic alkalis, and is ideal for welding and brazing operations.
