Nickel/Copper Galvanic Corrosion?

[Daniel Johnson]

I'd just like to confirm whether or not using copper radiators with nickel tubing would cause any kind of corrosion of either metal, like there is when aluminum and copper mix?

Thanks guys

There shouldn't be a problem with nickel and copper like there is with aluminum/copper. Is the tubing solid nickel for sure or is there a chance it's nickel plated? If it's plated, what is the base material being plated? I believe it's more common for nickel to be used as a plating over copper or aluminum than to be solid nickel.

It's Monel 400, which I believe is a copper-nickel mixture, not really a plating

seems to be mostly copper and nickel, and just hints of iron and manganese

Shouldn't be the issue that aluminum and copper is. Nickel's fairly safe/inert from what I've heard and the remainder is copper with copper.

And what about Inconel 600 for the tubing? It's mostly nickel, chrome, and some iron, with hints of other metals - more information

I wouldn't think so but I'm not 100% certain. I'm not familiar with these metals. Mostly just tubing available for water cooling lines available on the market. It sounds like you have access to some various materials you may be able to fabricate with. Maybe these links can help?

I didn't think so either, I just wanted a second opinion. I'll take a look at those links though. Thanks
