Nickel 201

Principal Design Features

This is a lower carbon version of commercially pure (99%) nickel. The material does contain minor amounts of other elements, totaling less than 1%.


Electronic components, applications where spinning to form the product is especially desired. Chemical corrosion resistance in caustic solutions.


Machinability is basically the same as for Nickel 200. The 201 variety is softer and “gummy” but can be readily machined by conventional mean. High-speed-steel tools are recommended.


Easily formed by conventional methods. Nickel 201 is especially well suited to forming parts by spinning.


Weldable by standard means as was also the case with Nickel 200. However oxyacetylene welding should NOT be used with Nickel 201.

Heat Treatment

Anneal at 1650 F to 1300 F depending upon the degree of cold working and time at temperature.


Forging should be done in the range of 2100 F to 1200 F.

Hot Working

Hot working may be done in the range of 2100 F to 1200 F.

Cold Working

Cold working is readily accomplished with standard tooling.


Anneal at 1650 F to 1300 F depending upon time at temperature and amount of cold working that has been done.


Hardens only by cold working.
