Copper Nickel 90/10 Pipes and Tubes, also referred as Cupro Nickel 90/10 Pipe and Tube, are high performance and high performance copper-nickel alloys products with 90 and 10 alloys of copper and nickel respectively. The alloy is known as UNS C70600 on an international basis and is produced in compliance with ASTM B466 / ASME SB466.
Copper Nickel 90/10 Pipe and Copper Nickel 90/10 Tube have been widely used in marine, offshore, desalination systems and heat exchanger systems owing to the superior ability to resist seawater corrosion, biofouling as well as stress corrosion cracking. Nickel addition has had a big contribution to the durability without compromising on the thermal conductivity and therefore, Cu-Ni 90-10 Pipe and Tube is best suited in situations where the continuous transfer of heat is required.
Cupro Nickel 90/10 Pipe and Tube is more workable, easy to fabricate and has a long service life in saline aggressive conditions than higher-nickel grades. The following properties ensure Copper Nickel 90/10 Pipes and Tubes are still used in condensers, ship constructions, oil and gas cooling lines, and power generation systems.
Our Copper Nickel Pipes and Tubes are supplied with complete traceability, mill test certificates and third party inspection at request.
