Pure Nickel Wires — Nickel 200/201
Nickel 200/201 — Excellent corrosion resistance for specialty industrial applications
About Pure Nickel Wires
Pure nickel wires offer outstanding corrosion resistance, high thermal and electrical conductivity, and excellent mechanical properties across a wide temperature range. Our pure nickel wire is available in multiple grades including N4, N5 (Nickel 201), N6, N7 (Nickel 200) and N8, each suited to different industrial requirements.
Nickel 200 (N7) and Nickel 201 (N5) are the two most commonly used grades. Nickel 200 is suitable for applications up to 315°C, while low-carbon Nickel 201 is preferred for higher temperature service to prevent graphitization. Both grades offer excellent resistance to alkalis, acids, and corrosive atmospheres.
Fine wire (0.025–1.6mm) is supplied on spools; coarse wire (1.0–10.0mm) is supplied in coils. Custom packaging and OEM labeling available.
