Hey all,
So I am in the process of building my first custom loop.
My plan is to use distilled water with either copper based Blue PT Nuke or a Kill coil (I've bought both, maybe I'll just use them both for good measure), but I have been wondering if anyone ever uses any kind of corrosion inhibitor additive, and if not, why not?
The materials in my loop are going to be Copper, Some Nickel plated Copper and - of course - the silver coil, so the Anodic indices I'm dealing with are as follows:
Silver: -0.15V
Nickel: -0.30V
Copper: -0.35V
Typical engineering guidelines are to keep the difference less than 0.25 for normal (warehouse condition) environments, less than 0.50 for tightly humidity controlled environments and no more than a 0.15 differnce for high humidity, outdoors or salty environments.
The loop isnt salty, but it sure as hell is high humidity, so I'm guessing the last 0.15V difference is the one that would apply here.
That means that without the silver kill coil I am more than fine with a difference of just 0.05v. Add in the kill coil - however - and my difference is now 0.20V, which is above the recommendation, and should result in slow degradation of the most anodic metal, the Copper.
So the querstion is, should I try to add a anti-corrosive agent to my fluid, just skip out on the kill coil and go only with PT Nuke to keep things below a 0.15V difference, or just nopt worry about it at all, because I am overanalyzing things?
What do you guys think?
