Alloy 405 (UNS N04405) is a nickel-copper alloy with high strength and toughness. Alloy 405 also has excellent corrosion resistance in a range of media including seawater, hydrofluoric acid, sulphuric acid and alkalis. Due to its increased sulfur content Alloy 405 has enhanced machinability. Alloy 405 is chiefly used for automatic screw machine stock and is not generally recommended for other applications.

Applications of Monel R-405 :
Alloy R-405 is chiefly used for automatic-screw-machine stock and it not generally recommended for other applications. Screw machine stock for fasteners and similar high production run items.
Meter and valve parts
Fasteners
Screw machine products
Characteristics of Monel 405:
Good machinability and is recommended for use with automatic screw machines
Resistant to seawater and steam at high temperatures
Excellent resistance to rapidly flowing brackish water or seawater
Excellent resistance to stress corrosion cracking in most freshwaters
Particularly resistant to hydrochloric and hydrofluoric acids when they are de-aerated
Offers some resistance to hydrochloric and sulfuric acids a modest temperatures and concentrations, but is seldom the material of choice for these acids
Excellent resistance to neutral and alkaline salt
Resistance to chloride induced stress corrosion cracking
High resistance to alkalis
