Monel 400 Springs

Monel 400 alloy is a nickel-copper solid solution strengthened alloy. The alloy is characterized by high strength, corrosion resistance, and toughness. It is particularly resistant to hydrochloric and hydrofluoric acids when they are de-aerated. Alloy 400 springs can be used in brackish or seawater applications.
