Cupro Nickel 90/10

Cupro Nickel 90/10
  • 90/10 Cupro Nickel is widely used in sea water. It has very good corrosion resistance to clean moderately polluted marine or estuary water, even containing dissolved incondensable gases.
  • This alloy is virtually immune from stress-corrosion cracking and hot spot denickelification.
  • In clean sea water, a velocity of up 2.2-2.5 m/s (7.5-8.5 ft/s) is accepted while 4 m/s (13 ft/s) is the upper limit for clean fresh or slightly saline solutions.

To avoid the risk of deposit attack, it is generally recommended to never operate at water velocities below about 0.8-1 m/s (2.5-3.5 ft/s). 90/10 Cupro Nickel can also be used, with appropriately reduced flow velocity, in contact with water containing some sulphides or suspended solids. It is also often selected for its good mechanical properties, both at room and relatively elevated temperatures.
