Why Are Koolance Blocks Gold-Plated? (It's not just for bling...)
There is a golden rule among water cooling enthusiasts: "never mix copper and aluminum". Koolance absolutely agrees with this IF both metals are exposed to liquid in the same cooling system.
However, there are many methods for reducing the likelihood of corrosion. For example, Koolance liquid coolant contains strong anti-corrosives. Koolance also employs another major strategy: we coat all copper in gold.
Gold is extremely stable, and strongly resists oxidation and galvanic corrosion both inside and outside the block. This also means gold presents an aesthetic advantage; it retains its luster. In contrast, bare copper oxidizes quickly and becomes blotchy with tarnish. (Note: the oxidized sample below was severely accelerated for thermal testing.)
