Metal corrosion?

Woodsie · 02-07-2002, 10:42 AM

Quick question...

I know that Copper & Aluminium don't like each other much, and putting zinc in with the water slows the corrosion down...

But, I've got an old fire extinguisher up for the taking (2 gallons), made out of mild steel...

Anything wrong (corrosion wise) with using it as a resivior in conjuntion with a copper waterblock?

Thanks in advance,

Barry

check out that table... the farther apart the metals are, the faster they will corrode. the metal will transfer from the anode (highest in list) to the cathode(lowest in list)

id say you would have some corrosion problem there if you used straight tap
