Seawater
Copper alloys are widely used in marine applications. Of these, the copper-nickels are perhaps the most important alloy family. Consequently, a quite extensive Copper-Nickel section is devoted to copper-nickel alloys and can be accessed by clicking on the copper-nickel heading on the right-hand side of this page.
Information on the other copper alloys, such as nickel aluminum bronze, is listed below.
Effects of Microstructure on the Seawater Jet Impingement Resistance of Nickel Aluminum Bronze
Nickel-aluminum bronzes are metallurgically complex alloys. Small variations in composition can result in markedly different microstructures. In a previous study, the microstructures of selected alloy compositions were characterized and correlated with seawater corrosion resistance. The present study discusses the results from seawater jet impingement tests conducted on these same alloy compositions.
Effect of Composition and Microstructure on the Seawater Corrosion Resistance of Nickel-Aluminum Bronze
Nickel aluminum bronze alloys were developed to minimize the occasional instances of selective phase attack or dealuminifaction observed in aluminum bronze under certain conditions. However, in order to attain the best combination of properties in nickel aluminum, its chemistry must be controlled. This paper illustrates the effort of alloy chemistry and heat treatment on microstructure. This, in turn, had an effect on quiescent seawater corrosion resistance.
Materials Selection for High Reliability Copper Alloy Seawater Systems
Seawater systems are used by many industries such as shipping, offshore oil and gas production, power plants and coastal industrial plants. The main use of seawater is for cooling purposes but it is also used for fire-fighting, oil field water injection and for desalination plants. This paper examines the use of copper alloys to provide high reliability systems covering piping valves, pumps, water boxes and strainers.
Guidelines for the Use of Copper Alloys in Seawater
Copper alloys are widely utilized in the design of seawater systems for their excellent resistance to corrosion and biofouling and many other excellent properties. This paper discusses general guidelines that should be considered when choosing copper alloys for service in a marine environment. Topics discussed include: protective film formation, effects of velocity, seawater cavitation, effects of sulfides, marine biofouling, stress corrosion cracking, galling and sizing resistance, and use in desalination environments.
Our Newest Section
Cu-Ni alloys are widely used for marine applications due to their excellent resistance to seawater corrosion, high inherent resistance to biofouling and good fabricability.
They have provided reliable service for several decades whilst offering effective solutions to today's technological challenges.
