Cupro Nickel 90/10 is a 90% copper, 10% nickel alloy that also contains small but significant additions of iron and manganese to improve overall strength and corrosion resistance. This combination, coupled with high ductility and toughness, makes it a popular grade for marine, structural, and industrial applications. It offers excellent resistance to stress corrosion, erosion, and biofouling in seawater and saline environments, along with superb fabrication and welding properties.
The alloy is known for its high resistance to hydrogen embrittlement and the retention of mechanical properties down to cryogenic temperatures. It is produced to the Defence Standard DEF STAN 02-879 Composition C, which supersedes both DEF STAN 02-779 and NES 779. The most notable specifications in Europe and America for this alloy are C70600, CN102, and CW352. These grades are widely used within the marine, offshore, chemical, petrochemical, and shipbuilding industries and are also extensively utilized for seawater handling in various heat exchanger and cooling plant applications.
