copper + nirosta, bad? or not?

[The Big One]

my friend is making a WC rig
he has a copper DD TDX water block
and a nirosta res (don't ask me why)

will it be a problem

i know that copper+alu = bad, very bad
but what about nirosta+alu?

I have no idea what "nirosta" is.

A quick Google search made me suspect it is stainless steel....is this right?

[The Big One]

think so

if it is stainless steal is should not be a problem, but make sure it is not aluminum.

If the rad is entirely stainless steel, I have a feeling that it's not going to be much of a performer...

If it's a stainless rez there is no short-term problem, but stainless will rust given the right circumstances.
