Sandblasting waterblocks - What should I know?

post #1 of 26
Thread Starter 
My father owns a sandblaster, so I was thinking about sandblasting my Koolance waterblocks just because of all the bad things that have been going on with nickel plating. I don't have the money to get new blocks, so sandblasting is an option. I haven't opened them in a while and the last time there was no issues, but when I do this time if there's issues I would like to sandblast them.

So what do I need to know with sandblasting. I can get the block apart, etc., but what do I need to know for after I sandblast them? Anything they should be cleaned with, etc.? After I sandblast them, they're just going to be copper right? Just want to make sure I know what I'm getting into smile.gif

Your going to create more issues than you solve I think. If there is even an issue.

Sandblasting is not a gentle process especially when your talking about taking off a nickel plating. The blocks that I have seen have pretty small features that are going to get either destroyed in the process or lose their effectiveness. I would think a chemical process would be better here. Not sure what would eat at nickel and not copper but again I think your in the realm of creating more issues than your solving.

The only important thing you need to know about sandblasting the inside of your water block is NOT to even consider it.

Hmm didn't think to get these kind of responses. Not that its a bad thing. I've just read through threads and people mention sandblasting the blocks if they're corroded. If anyone has any experience id like to know anyways. Thanks for the reponses thus far.

In theory, if done properly and evenly, it shouldn't be a problem. You have to make sure they start with medium to high grain sand and that they blast it evenly or you will end up with an uneven surface. The thing is, why even risk it? It is much easier and safer to simply wet send the corroded layer off.
