I'm pretty sure the kill coils are pure silver because anything less starts messing with how it acts as a biocide, but the rest of those you don't know their exact makeup. What's more, you're forgetting other things like what is your radiator solder makeup; or if you have a D5 or certain reservoirs or water blocks, there is stainless steel there as well. What are your fittings made from? In the end, it is easier to just use trial and error (within reason) and then add a corrosion inhibitor if you need one. Even Nuke PHN slightly inhibits corrosion (maybe to 325 or 350mv? I've not seen any specific tests).
Since these components are designed for water cooling, you can expect that as long as you use your head, you should be ok. You're likely not going to be able to find out what any of the manufacturers actually use for their materials because sometimes doing so might prove that they are using a faulty plating process or a cheap alloy. The moral of the story is that you _might_ have some corrosion issues, but if you try to match your metals well you really shouldn't have a problem.
