Is anodized aluminum that bad when mixed with copper?

[Gabriel Noraa]

Even if you feel like you can trust a companies anodized aluminum, take a look to what happened to my dual Swiftech MCW5000s (copper base / alu top).



And check the interior of the BIX I , that was also in the same loop as the blocks.



I was using 90% H2O + 10% Engine Coolant.

For me, mixing Aluminium and Copper/Bras in the same loop it's totally forbiden. Never again.
