Nickel

Commercially pure or low alloy nickel finds its main application in chemical processing and electronics. Compared to nickel alloys, commercially pure nickel has high electrical conductivity, a high Curie temperature and good magnetostrictive properties. Nickel also has good thermal conductivity. This means it can be used for heat exchangers in corrosive environments. In case mechanical parts require excellent corrosion and strong magnetic properties, pure wrought nickel is a best option among materials with high ductile properties at wide range of temperatures.

Produced materials

  • Nickel 200 (UNS N02200 / 2.4060/ 2.4066) – is a wrought nickel with compositional adjustments to enhance the performance in electronic applications.
  • Nickel 201 (UNS N02201 / 2.4061/ 2.4068) – excellent resistance to many corrosion media and simplicity of welding allows using this materials in many industries.
  • Nickel 205 (UNS N02205 / 2.4061) – it is most commonly used for the anodes and grids of electronic valves, magnetostrictive transducers, lead wires, transistor housings and battery cases.
  • Nickel 212 (2.4110) – it is used in lead wires, supporting components in lamps and cathode-ray tubes, and electrodes in glow-discharge lamps.
