We also provide the customization of chemical composition, size, shape, and finish to particular project requirements. Please contact our team in case of technical questions or price information.
About Copper Nickel Pipes and Tubes
Copper nickel alloy, or cupronickel as it is commonly referred to, is a versatile material composed mainly of copper with moderated additions of nickel, iron, manganese, as well as other elements. The copper nickel alloys, even though they have a significant amount of copper, still have a unique silver look, and that is why they can be used for functional and aesthetical purposes. Copper nickel pipes and tubes are used in marine applications for manufacturing of propellers, propeller shafts, and boat hulls as they resist seawater corrosion and biofouling. Copper nickel condenser tubes find extensive application in petrochemical facilities, power generation facilities, electrical systems and defence systems. When cupro nickel tubing is provided in an annealed state it has a natural resistance to macrofouling, high tensile strength, and high ductile characteristics. These tubes preserve their mechanical properties to cryogenic temperatures and offer antimicrobial surface properties and so, are applicable in hygienic and critical fluid-handling systems.
Grades of copper nickel pipes and tubes are C70600 (90/10), C71500 (70/30) and other combinations depending on the proportion of copper and nickel. Copper Nickel 90/10 pipes are used in seawater applications, whereas Copper Nickel 70/30 pipes have more strength, better oxidation resistance, and work better in high temperature and high velocity environment. Copper nickel tubes are also offered in a large variety of sizes, wall thicknesses, and specifications to suit a wide variety of industrial requirements. The supply may be in form of copper nickel pipes and tubes that have a seamless quality finishing which guarantees consistency in the performance of products in extreme operating environments.
Copper Nickel Pipe & Tubes Grades
Copper Nickel 70/30 Pipes And Copper Nickel 70/30 Tubes
Copper Nickel 90/10 (UNS C70600), which contains approximately 90% copper and 10% nickel with small additions of iron and manganese. This grade offers excellent resistance to seawater corrosion, good thermal conductivity, and easy fabrication.

Documentation You Can Expect with Your Copper Nickel Tube Order
To buy Copper Nickel Tubes & Pipes, connect with the trusted copper nickel pipes & tubes suppliers & manufacturers where full documentation should be issued to get quality, compliance and traceability. Typical documents include:
- Material Certificate: These certificates attest to the fact that the Copper Nickel Tubes are of international standards like ASTM or ASME. They give comprehensive data of the chemical composition and mechanical property of the material.
- Test Reports: Test reports can also contain tensile strength, hardness, and corrosion resistance tests, which prove that the tubes are at the necessary quality and performance standards.
- Shipping Documents: Papers such as the bill of lading, invoice, packing list and shipping information give a full history of your order and also assist in tracing the shipment of the manufacturer to the location where you receive them.
- Welding Certificate and Inspection Certificate: In the case of welded Copper Nickel Tubes, such certificates confirm that the welding and inspection were done in line with industry standards and hence the structural integrity and reliability.
- Warranty Information: Authoritative manufacturers of copper nickel pipes will have warranty information on defects or performance failure and hence you will be assured on the lifespan of your tubes.
- Compliance Certificates: When you are using tubes used in the marine or offshore or any other regulated use, then compliance certificates are used to assure that products are in line with the required industry regulations and standards.
