Ni 201 and Ni 200 are also known as Nickel Alloy Ni-201 and Commercially Pure Nickel, Ni 201.  Ni 201 only differs from Ni 200 by its carbon content (.02% max in Ni 201 versus .15% max in Ni 200). This slight drop in carbon allows Ni 201 to be utilized in higher temperature applications (over 600°F) including:

  • Handling and manufacturing sodium hydroxide above 300°C
  • Soap manufacturing
  • Viscose Rayon manufacturing
  • Production of benzene, methane, and ethane
  • Reactors and vessels

Like Ni 200, Ni 201 offers a wide range of benefits to users including:

  • It can be hot-formed in an almost unlimited number of shapes
  • Cold rolled under proper conditions
  • Highly resistant to various reducing chemicals
  • Outstanding resistance to caustic alkalis
  • Good electrical and magnetostrictive properties
  • High electrical and thermal conductivity
  • The toughness of nickel

Ni 201 is composed of roughly the same chemicals as Ni 200 except for the aforementioned difference in carbon content.

  • Ni 99% min
  • Fe .40% max
  • Mn .35% max
  • Si .35% max
  • Cu .25% max
  • C .02% max
