For steam ships, such as nuclear powered ships or lng tankers, copper-nickel is a candidate material for the condensers and seawater systems. the use of scoop intake systems on steam turbine powered ships normally require 70-30 or 66-30-2-2 cu-ni alloys with high resistance to impingement corrosion.
Copper-nickel is widely used in high pressure systems operating at over 105 bar 1500 psi and especially where there is an additional need for corrosion resistance or low temperature capability. the ease of forming of the alloys into complex fittings and coils have ensured their continued selection.
This generated a large amount of data, but in the 1990s, nickel-metal-hydride nimh took over the reign to solve the toxicity problem of the otherwise robust nicd. many of the characteristics of nicd were transferred to the nimh camp, offering a quasi-replacement as these two systems are similar.

Copper-nickel tubing, such as cunifer or nicopp, offers what appears to be a miraculous alternative.despite being an arguably softer material than steel, its dot approved for hydraulic use. in fact, its psi ratings are only a little lower than that of steel, still more than strong enough for brake applications, which typically see a maximum of anywhere from 800 to 1,500 psi.
