Mixing metals in wc bad?

Harbz · 17 Jun 2007 at 15:16

I am currently buying bits for my new WC setup. Purchased a couple of heater cores from ebay, and ehiem pump. The heater core are made from aluminium while cpu blocks are copper. Will this metal mix cause adverse effects?

thanks.

It can cause galvanic corrosion but use some Zerex or similar and it *should* be OK.

I now have a copper block, 2 aluminium heater cores and a thermochill pa120.3 (copper?). Not sure how much of a dangerous mix this is in terms of corrosion. Should i dump the heater cores and just use the thermochill? Or will anti corrosion addative stop the corrosion?

anti corosion additives will help.

even a good dose only slows the effect tho.
then again, my friend has been using an alu heater core and copper maze 3 for several years, the maze 3 is starting to get discoloured and looking a bit worse for ware, but not horribly so, and performance isnt hurt.

Do you actually need the heater cores along with a PA120.3?

You can mix them but will need preventative addatives as stated and more frequent maintenance.

Since Harbz has bought the components already he may as well make the most of it. In Harbz' circumstances I would say yes.

This is what will happen to your aluminium heatercores.
