Nickel Alloy 200

Nickel Alloy 200

Nickel 200 (UNS N02200/W.Nr. 2.4060 & 2.4066) is commercially pure (99.6%) wrought nickel. It has good mechanical properties and excellent resistance to many corrosive environments. Other useful features of the alloy are its magnetic and magnetostrictive properties, high thermal and electrical conductivities, low gas content and low vapor pressure. The corrosion resistance of Nickel 200 makes it particularly useful for maintaining product purity in the handling of foods, synthetic fibers, and caustic alkalies; and also in structural applications where resistance to corrosion is a prime consideration

Applications

Typical applications are:

  • Food manufacturing such as handling of cooling brine, fatty acids and fruit juices due to the material’s resistance
    against acids.
  • Alkalis and neutral salt solutions and against organic acids.
  • Tanks in which fluorine is produced and where it reacts with hydrocarbon (CFC) due to the material’s resistance
    against fluorine.
  • Storage and transport of phenol.
  • Production and treatment of caustic soda.
  • Production of synthetic fibers and soaps.
  • Production of hydrogen chloride and chlorination of hydrocarbons such as benzene, methane and ethane.
  • Production of vinyl chloride monomer due to the material’s resistance against dry chlorine gas and hydrogen
    chloride in increased temperatures.
  • Electrical and electronic components.
  • Electrode contacts and current conductors in batteries.
  • Current conductors in alkali fuels
