DETAILED INFORMATION

Q: What is Copper Nickel 70/30 Round Bar?

A: Copper Nickel 70/30 Round Bar is a solid cylindrical bar made from an alloy of 70% copper and 30% nickel. It offers a unique combination of excellent corrosion resistance, high strength, and good thermal conductivity.

Q: What are the key features of Copper Nickel 70/30 Round Bar?

A: Copper Nickel 70/30 Round Bar exhibits exceptional resistance to seawater corrosion, biofouling, and erosion. It has high ductility, making it easy to fabricate and form into various shapes. It also has good weldability and can withstand extreme temperatures.

Q: What are the applications of Copper Nickel 70/30 Round Bar?

A: Copper Nickel 70/30 Round Bar finds extensive use in marine environments, particularly in shipbuilding and offshore structures. It is commonly used for seawater piping systems, heat exchangers, condensers, desalination units, and various other marine equipment. It is also employed in the chemical industry, power generation, and desalination plants.

Q: What are the advantages of using Copper Nickel 70/30 Round Bar?

A: Copper Nickel 70/30 Round Bar offers several advantages, including excellent resistance to corrosion in seawater and brackish water, high resistance to biofouling and stress corrosion cracking, good strength and ductility, and outstanding resistance to erosion and impingement.

Q: What is the recommended temperature range for Copper Nickel 70/30 Round Bar?

A: Copper Nickel 70/30 Round Bar can operate effectively in a wide temperature range, from cryogenic temperatures up to 400°C (750°F). It retains its mechanical properties and corrosion resistance even at elevated temperatures.

Q: How is Copper Nickel 70/30 Round Bar fabricated?

A: Copper Nickel 70/30 Round Bar can be easily machined, fabricated, and welded using standard techniques for copper alloys. It can be cut, drilled, bent, and formed into the desired shape. However, it is important to use tools and equipment specifically designed for copper alloys to prevent contamination.

Q: Is Copper Nickel 70/30 Round Bar suitable for saltwater applications?

A: Yes, Copper Nickel 70/30 Round Bar is highly suitable for saltwater applications. It is widely used in the marine industry due to its exceptional resistance to seawater corrosion, which helps prevent the degradation of equipment and extends its service life.

Q: Does Copper Nickel 70/30 Round Bar require any protective coatings?

A: Copper Nickel 70/30 Round Bar does not require any additional protective coatings, as it forms a protective oxide layer on its surface when exposed to seawater. This natural oxide layer helps inhibit further corrosion and provides long-lasting performance.

Q: Can Copper Nickel 70/30 Round Bar be used in contact with other metals?

A: Copper Nickel 70/30 Round Bar can be safely used in contact with other metals, including stainless steel, carbon steel, and aluminum. However, it is important to consider galvanic corrosion and employ suitable measures, such as insulating gaskets or dielectric flanges, when connecting it to dissimilar metals.
