Like many, I am working on my first WC project. I keep reading that mixing metals is bad because of corrosion. What about brass & copper though? Copper blocks and brass fittings, etc... are these to metals an exception?

thanks

Brass is just a Copper/Zinc alloy. I've personally never had any corrosion problems from my brass fittings.
 
the corrosion you have to worry about it usually from aluminum and copper,brass etc... Sometimes radiators coem in aluminum so just be on the lookout for that.

I also have never had corrosion problems with my copper blocks, rad with my brass fittings. You shouldn't have any problems with bronze either, and silver is pretty friendly with the copper family in case you were looking into any silver blocks as well.
 
i dont plan on using silver waterblocks, from what i read they arent worth the extra cash. currently im comparing the TDX and RBX and possible a third choice if i run into something better in my budget.

im getting a heatercore from 2Fresh, so looks like i wont need to worry about silver there either. thanks for the help.
 
Galvonic corrosion shouldn't be a big issue if you use a quality additive like Zerex or something. Also, it's noteworthy to mention that the cooler your loop runs, the less corrosion will occure. I use Zerex and chill my water and at 17*C, 1 year and not a sign of corrosion.
