	Whipple Industries
		Whipple’s cupronickel, pronounced koo•pro•nik•el, is a space age technology that utilizes a unique blend of pure copper alloy air fins for increased thermal efficiency over aluminum and cupronickel water passages for maximum corrosion resistance.
		Some utilize “chromacoat” or anodized cores, which will still corrode over time, only cupronickel will last in the brackish lake waters and ocean salt water because of it’s electronegativity is adjusted to neutral with regard to seawater.
		Whipple cupronickel intercoolers can not only withstand salt water, but it has a melting point of over 2000deg F, has large water passages to allow less chances of clogging, comes with billet tanks and tig welded construction.

	CTL-Denickelification of Cupronickel Tubing in an Oil Refinery
		One tube segment from a failed tube was sent to CTL for failure analysis.
		This pitting was caused by denickelification of the cupronickel structure, Figure 2, commonly referred to as plug-type denickelification.
		As discussed in the Technical Brief: Denickelification of Cupronickel Tubes, cupronickel tubes get their corrosion resistance by the formation of a passive oxide film on the exposed surface.

	Nickel Industry's Response
		Both cupronickel and nickel are excellent production materials for coins being easy to produce, shiny and corrosion resistant in normal use, and capable of very long useful life.
		Nickel and cupronickel usually do not pass this release test so their use in such applications is inappropriate if the nickel or cupronickel surfaces are designed to be in close and prolonged contact with the skin.
		But all of this does not mean that nickel or cupronickel is unsuitable for use as a coinage material where, in normal handling and use, contact with the skin is short and intermittent, not prolonged.

	Thunder Horse
		Copper/nickel, or "cupronickel" as it is sometimes called, is also highly resistant to uniform corrosion at ambient temperatures, and the average depth of pit penetration does not increase continuously over time.
		Cupronickel is less resistant to erosion and corrosion than other materials at higher seawater velocities, but those same corrosion- and erosion-resistant materials are often susceptible to localized corrosion in standing seawater.
		Marine organisms are intolerant of the cuprous ions cupronickel releases, and because bio-fouling adheres only weakly to the passive film that develops on the metal's surface, it sloughs off.

	cupronickel \| \| Dictionary & Translation by Babylon
		Cupronickel does not corrode in seawater, because its electrode potential is adjusted to be neutral with regard to seawater.
		Because of this it is used for marine hardware, and sometimes for the propellers, crankshafts and hulls of premium tugboats, fishing boats and other working boats.The most ubiquitous use, from the point of view of the average person, is that most of the silver-coloured modern circulation coins are cupronickel.
		Le cupronickel est un alliage de cuivre et de nickel, reconnu pour ses proprétés anti-corrosives et d'anti-fouling.

		A leakage was observed from 90/10-cupronickel tube bundles containing seawater as coolant, in the condenser unit of a heat exchanger.
		The seawater was chlorinated to suppress microbial activities and also dosed with ferrous sulfate (FeSO4) to counteract possible sulfide and chlorine-accelerated corrosion of the cupronickel alloy.
		The primary cause of the pitting corrosion is the continuous entrapment of aggressive sulfide species under deposits on the tube surfaces.
