Application
Seawater Piping Systems: These alloys are used in marine piping systems, pump shafts, water boxes, marine fixtures, and fasteners due to their excellent resistance to seawater corrosion.
Desalination Plants: Components in desalination plants require materials resistant to harsh seawater environments, making UNS N04400 and UNS N04405 ideal choices.
Equipment and Piping: Used in manufacturing equipment like heat exchangers, reactors, and columns that handle acids and alkaline media and are exposed to corrosive environments.
Pumps and Valves: Due to their corrosion resistance, they serve as components in pumps and valves that are in contact with corrosive chemicals and are often made from these nickel-copper alloys.
Offshore Oil Rig Components: For components exposed to marine environments, such as safety lifts and firewater systems, these alloys are preferred for their strength and corrosion resistance.
Sour Gas Service: Equipment used in the processing of sour gas benefits from these alloys’ resistance to sulfide stress cracking.
Feedwater Heaters and Steam Generators: These alloys are often used for components within steam generators and feedwater heaters that require resistance to corrosion and high temperatures.
Electronic Components: These alloys are used in electronic components and connectors due to their excellent conductivity.
Aerospace Components: The alloys find applications in aerospace structures for parts requiring high strength and environmental corrosion resistance.
Automotive Applications: For sensors and other critical components exposed to corrosive environments or requiring high conductivity.
