HPM® 201 Nickel • UNS N02201

HPM® 201 Nickel is a commercially pure wrought Nickel. With low carbon, the material has excellent corrosion resistance with high thermal and electrical conductivities.

The alloy can be formed by all conventional cold-forming methods and can be joined by welding, brazing and soldering. The corrosion resistance is generally very good in most mediums, although it is subject to intergranular embrittlement by sulfur compounds above 315°C.

Available Sizes:

HPM® 201 Nickel is available from Hamilton Precision Metals as strip product in thicknesses from 0.0005” to 0.020” (0.0127 mm to 0.508 mm) in widths up to 12.0” (304.8 mm). It is available as foil as thin as 0.000100” (0.00254 mm) to 4.0” (101.6 mm) maximum width. The material conforms to ASTM B162, and UNS N02201.
