What is the difference between Nickel and Copper?

All water block cooling heads are made of bare rods of electrolytic copper. These rods are milled using a precision guided CNC machine to make a bare copper water block (cooling head) base.

Nickel electroplating is a technique of electroplating a thin layer of nickel onto a metal object. Nickel plated water block it means the product is coated with the fine layer of nickel after the milling. The bare copper bases are therefore applied with fine thin layer of nickel coating in a submersion bath. The nickel layer is decorative and can provide corrosion- and wear resistance.

So-called 'Nickel water block' is still a pure copper water block, but plated with a layer of nickel. Performance wise the nickel plated water block is identical in performance to non-plate (bare) copper water block.

    "Performance wise the nickel plated water block is identical in performance to non-plate (bare) copper water block."

    How is that possible, when the thermal conductivity value for Copper is 4 times the value of Nickel ??

    Yeah... about that, a thickness of about 0.3 MICROmeters (or so i suspect that's the thickness ek uses) won't make any difference worth even mentioning.

    Electroplating is such a thin amount of material around the bulk material that it has a statistically insignificant affect on it's thermal conductivity. In fact one could argue that nickel plating is actually superior as the copper oxide layer that can form looks terrible and has more of an impact on the cooling than the nickel plating which stays shiny throughout its useful life time.
