Nickel 201
UNS N02201
Werkstoff – Nr. 2.4066/ 2.4068
DIN 17752/ DIN 17750/ DIN 17753

Nickel 201 is commercially pure nickel. High purity of Nickel leads material to extreme malleable and ductile properties and increase life period significantly. Nickel 201 has high electrical conductivity, Curie temperature and good magnetostrictive properties. A commercially pure Nickel 201 is essentially the same as Nickel 200, but with a lower Carbon content to prevent embrittlement by inter granular carbon at temperatures over 315°C (600°F). Lower carbon content also reduces hardness.

Nickel 201 (2.4066 / 2.4068) – can be melt with 99.7% of nickel.

Excellent resistance to many corrosion media and simplicity of welding allows using this materials in many industries. Nickel 201 can be used at higher temperatures and has resistance from being embrittled by intergranular precipitates at temperature from 315°C to 750°C:
  • chemical and food industries
  • electrical parts and electronic components
  • metallurgy and machinery
  • aircraft gas turbines
  • nuclear power systems and Steam turbine power plants
  • medical applications
