hi everyone, i have a question. Does aluminum react to silver or nickel plated brass? reason is because i can't really find any copper to make a waterblock, so i'm going to use aluminum. My dad taught me how to use a mill, so i'm going to make an aluminum waterblock. However, 95%of barbs are made out of nickel plated brass, and i'm kinda scared of galvanic corrosion happening there. Secondly, i need a piece of silver because of its biocidal properties. will that also cause corrosion?
thanks!
wait...
you can get silver but not copper?
Something about that sounds really wierd

well, i need 1 ounce piece of silver for a biocide cause i don't like other addictives. 1 ounce= 20 bucks usd
Agreed, it's weird to not be able to find copper... However, if it is just to make a prototype where you aren't sure about the measurement, getting aluminium should be cheaper...
i am planning on having a pure aluminum loop, with some of bitspower compression fittings which are nickel plated brass, and a 1 ounce piece of silver as a biocide. Will there be any corrosion? i know that brass/copper and aluminum will corrode, but will nickel plated brass and aluminum and silver corrode?
Redox! Look up the relative oxidation/reduction values, and do half reactions to see if they will act as an electrolytic cell.

nothing wrong with an entire alu loop expecially if you draft it from scratch.Originally Posted by Boogerlad
koolance radiators could act as a heat exchanger.
Lemme see... Alu might be a good way to start, and then jump to copper.
You should pm martin and ask him where he buys his slab. i remember him showing me and they sold it for a good price.
why cant you aquire copper? where you located at?

i am in canada, ontario, and i am not even done grade 8 yet lol, so i dont quite understand you cegras. My dad has a nice machine shop and has taught me how to mill and stuff, but he only has bronze, aluminum and steel.
LOL nice start!
Well start practicing on the ALu. As i said you can use a koolance radiator as a heat exchanger.
After you get some skillz, and you want to attempt on copper, ask your dad for a little slab. They dont cost very much.
And chances are if you tell your dad you have a project you want to run with copper, he will most likely get you a little slab to play with. Its not super expensive.

Haha, don't worry about it, it seeps out of my head on occasion too.
If you're worried, I think nickel is quite inert .. so it's okay to mix. Copper and Alu aren't good because they're pretty strong reducing/oxidizing agents, forgot already.
Just keep it one metal : P

anyone know of any good aluminum heatercores and barbs?
Koolance FTW! ROFL....
no seriously tho, almost any barb will do. Dont crack the plating.
As for the radiator look at the koolance website. Thermaltake TMG makes a BIP wannabe thats made out of alu. Thats another solution.
If worse comes to worse, you can always find a used reserator. People are getting rid of those on ebay fairly cheap.

Make your own barbs
As for a rad, most car radiators these days are aluminum so they might be a good way to go.
Any metal salvage yards should have copper. $2/lb probably.
All along the watchtower the watchmen watch the eternal return.
is copper sulphate okay with aluminum, or do i need to find other biocide? i have mill and lathe, but i don't know how to use the lathe.
what do you guys think will be the smallest pin size that i could got to with a 1/8th endmill?
+1Make your own barbs
The nickel plating will pose a problem.

thanks everyone. Now i have my copper =) BTW, do you think that copper and carbon fiber will have a galvanic reaction? i dont think it will cause cf is a plastic and most plastics are neutral, but i just want to make sure. cf would make a great top material.

Metal and CF is no problem. FWIW, Silver and Aluminum is worse than a Copper and Aluminum mix.

Carbon-Fibre isn't plastic - it's fibres of pure carbon, and extremely electrically conductive. But yes, the stuff you get as sheets is set into a polyester or epoxy resin, so the only thing that should come into contact with the water will be plastic.
is that because silver is higher on the galvanic table of nobleness?
Yes, exactly

then isn't nickel and copper/brass a bad idea? theoretally, it would corrode, but it doesn't corrode on people.
