Nickel Corrosion? Kill Coil copper coloured

post #1 of 56
Thread Starter 
I just drained and refilled my loop and happened to notice that the silver kill coil in the bottom of the res has turned a copper colour. I have a Phobya Balancer 150 silver nickel res and I believe that the nickel is plated onto a layer of copper which is plated onto the brass base.

I can see a tiny area where the nickel either wasn't there in the first place or it's flaked off. Is this the first signs of a problem?

I'm not sure, but that looks like straight up rust.

Silver doesn't rust, it tarnishes but iirc silver tarnish is bluish. Now, it could be that his coil isn't silver and is instead plated copper... hmm?

I guess I should have elaborated... It looks like rust..meaning there's something in the loop that is rusting, or perhaps his coil is actually not Silver... To me, that looks like rust. The color, the whole way it looks...just looks like rust to me. Not a good sign, either way.

Oh man, that's cheap (not you, the manufacturers ), gotta agree with tsm, looks like copper plated in silver.

Do you know who made your coil? Do you have an order confirmation e-mail for it by chance?

Only real way to tell would be to take something like a stanley blade to it and scratch the surface off.

Yeah, which back-street gypsy did you purchase this from? It wasn't from BK, was it? You know, EK's sisters company that makes Jewelry....

Welp, if it ain't copper showing up... he's gonna have some galvanic corrosion if he's on distilled and a coil only. OUCH! In this instance, I'd hope it's a cheap copper with silver plating.

It's a Pulse Modding silver coil 99.9% available for sale at most of the main UK Water cooling suppliers.

I've posted this on another forum and the consensus there seems to be that it has to be 99.9999% purity not 99.9% for it not to react this way.

I put this coil in the loop when I added the res so it's in the 3 weeks it's been in the loop that it's picked up the copper. The previous kill coil was fine with all other components that have been in the loop at least 3 months in the case of the Kryos, 6 months for the EK blocks and over a year for the fittings. The problem is that as they went in the loop at the same time it's difficult to be precise about the problem. I will say that there's no sign of corrosion at all on the res where the plating has been removed which was probably by machining during manufacture to make the anti-cyclone plate fit into the res base.

The copper scrapes off the coil leaving a silver colour underneath.

As someone else said, I'd be curious to see if it's actually copper you're scraping off or rust.
