Mixing Aluminum with copper

Someone told me that if i mix Copper and Aluminum components in my water cooling system ,some sort of chemical reaction would occur.If anyone has any idea of what actually happens ,please spread thy wisdom.
(I run the system with room-temp water)

  1. If you have an aluminum radiator and a copper heatsink this can give problems. There will be some kind of reaction (electrolysis) between the metals which can ruin the heatsink/radiator. You can prevent this by adding some WaterWetter to the water, or using antifreeze (but that decreases the waters heat transporting ability, while WaterWetter highers it) or using distilled water.

    My case has so many fans that it hovers above the ground :eek: .
  2. Thanks man, this brings me to the next question: Where to get Waterwetter in europe ? (preferably a cheap company that ships to finland).Again , all responses are welcome.
  3. I bought mine by <A HREF="http://www.oc-shop.com" target="_new">http://www.oc-shop.com</A>, but I don't know if they ship to Finland.

  4. You might be able to get Water Wetter from a large automotive supply store. It is used mostly as a coolant in race cars.

    As for using distilled water, don't count on it. As soon as the water touches the metal it picks up metal ions, thus re-ionizing (or un-distilling) itself.

  5. If possible, stick a zinc anode (from any marine supply store) in the aluminium chunk. If the aluminium chunk is the radiator see if it has a drain plug you can replace with an anode

    There is another solution if you can't screw it in but I won't go into it unless your interested.
