Designated as UNS N02200 & W.Nr. 2.4060 & 2.4066, Nickel 200 or Ni 200 is 99.6% commercially pure wrought nickel. Nickel 200 has excellent resistance to many corrosive environments and good mechanical properties. Other useful features of Nickel 200 are its magnetic and magnetostrictive properties, low gas content, high thermal and electrical conductivities and low vapor pressure.

Designated as UNS N02201 or W.Nr. 2.4061 & 2.4068, Nickel 201 is has almost identical chemical composition as Nickel 200 except the lower-carbon content. Nickel 201 is typically applied in caustic evaporators, combustion boats, plater bars, as well as electronic components. Compared to Nickel 200, Nickel 201 has much lower base hardness and lower work-hardening rate hence is particularly suited for spinning and cold forming. According to ASME Boiler and Pressure Vessel Code Section VIII-Division 1, Nickel 201 is approved for construction of pressure vessels for service up to 1250°F. Its mechanical properties also vary depending on the manufacture process and heat treatment conditions.
