Pure Nickel
Nickel 200 (UNS N02200) — Composition, Properties & Supply
Nickel 200 (UNS N02200) is commercially pure nickel with at least 99.0% Ni. It offers excellent resistance to caustic alkalis, good electrical and thermal conductivity and high ductility, and is the standard material for chlor-alkali plant, electronic components and food processing equipment.
What is the chemical composition of Nickel 200?
| Element | Symbol | Content (wt%) |

Frequently asked questions
Should I choose Nickel 200 or 201?
Use 200 (C ≤ 0.15%) below 315 °C. Above 315 °C carbon precipitates as graphite at grain boundaries and causes embrittlement, so the low-carbon 201 (C ≤ 0.02%) is mandatory, extending usable temperature to 600 °C.
