Worried about galvanic corrosion

post #1 of 23
Thread Starter 
OK so I can't seem to find any concrete facts on this... So I'm going to ask the experts hahah.

I'm a few days away from putting together my first loop, have almost everything ready but still a few questions...

Loop will have 1x RX 360, 1x EX 240, 1x XSPC Acetal CPUWB, 10x Brass fittings (Chrome plated i think), Silver Killcoil and a Koolance Nickleplated drain thing.

Will I get corrosion? Koolance stated on their website that "Additionally, do not use aluminum with bare (unplated) copper or bare (unplated) brass in the same system. Do not use nickel with silver in the same system."

I haven't bought the Koolance drain yet and I will have silver in my system, so should I take the warning seriously or is nickle+silver nothing to worry about?

IMO there are too many variables to be sure about nickel plating. There are differences in plating quality as well as differences in what users put in their loops. Many do just fine with out a corrosion blocker and are perhaps lucky while others have plating failures. The only thing certain is that now pretty much all the nickel plating manufacturers are recommending that you either use their coolant or something with a corrosion blocker when running plated parts. Corrosion is present in all loops, but solid copper parts don't have anything thin that can peel or flake so you are safe with bare copper.

I have run nickel plated blocks myself with just water and ptnuke without problems, but any more I wouldn't guarantee it. If you really want the most corrosion protection possible with plated parts you best bet is to follow the manufacturers recommendations an run thei coolant or some sort of corrosion blocker. Also regular flushing and cleaning and inspection of the parts is always a good thing.

I would suggest bare copper parts for distilled loops and a corrosion blocker for plated copper.

you can use a simple t-port for a drain port, instead of koolance's fitting.

Basically, don't mix aluminum and copper. That's all you need to worry about!

Silver does actually have the potential to cause galvanic corrosion with nickel, their warning is reasonable... I'd skip on the silver or run some kind of corrosion inhibitor. It's nothing guaranteed to happen, but IMO better safe than sorry. I think the alternative biocides I've seen recommended for use with nickel are copper sulfate-based.

Per Koolance web site here
Quote:
Use of 3rd-party replacement parts, coolants, or coolant additives will void this warranty.

liquid utopia that you linked to would be fine for corrosion inhibitors, except it voids the warranty for Koolance nickel, so like Martin said, if you want to maintain the warranty have to stick with same brand coolant.

I think manufacturers need to make nickel plating on outside of blocks only, and leave bare copper for areas in contact with cooling fluid. Mass produced, cheap, thin nickel plating is only useful for aesthetics anyways, so for blocks other than clear acrylic, it makes no sense to use cheap nickel plating. Nickel plating is only good at reducing corrosion/oxidation if plated at 20+ microns with some type of hardening and proper prep work which apparently is difficult to maintain at the price point. Cheap 4-8 micron thick platings doesn't qualify for anything other than looks, and often even that doesnt last long in our loops, and in cases only weeks.

Stick with copper, brass and chrome. I have been using this combination for years with no corrosion whatsoever and using straight distilled water. I have disassembled my copper block after 1 year of use and it was as clean as the day I installed it.
