Monel® 400 Nickel Bar

UNS N04400

Nickel Alloy 400 and Monel® 400, also known as UNS N04400, is a ductile, nickel-copper based alloy comprised essentially of two-thirds nickel and one third copper. Nickel Alloy 400 is known for resistance to a variety of corrosive conditions, including alkalies (or acid like substances), saltwater, hydrofluoric acid and sulfuric acid. Other advantages of using this alloy are its toughness and high strength over a broad temperature range; it can also be manipulated to become magnetic if desired. Fortunately, if Nickel Alloy 400 doesn’t meet your specific needs, NSA stocks other nickel-copper based alloys to choose from.

Industries that use 400 include:

  • Chemical
  • Marine

Products partially or completely constructed of 400 include:

  • Electronic and electrical components
  • Fresh water and gasoline tanks
  • Heat exchangers
  • Marine hardware and fixtures
  • Process piping and vessels
  • Propeller shafts
  • Pumps
  • Pump shafts
  • Springs
  • Valves
