Jesus H dude... Is it really that important?

You are right.. 90/10, 80/20 or 70/30 CuNi does not contain chrome...

I was suggesting that using an IC of 304 SS could potentially pose more of a health concern because of the chrome.

That being said - neither are an issue assuming you don't have a practice of grinding portions of the chiller to an airborne dust, snorting it, while also immersing it into hot wort.

Better?

It sort of is, in a thread already full of misunderstanding and near-on fear mongering it is just adding more fuel to the fire.
It was a fair comment to ask for you to be more specific when you had accepted that you should have been more specific but did actually go on to be more specific.
The OP already thinks he is going to die from Ni(CO)4 if he makes the chiller, now he's going to get cancer too.

Pretty much make the assumption that if you come on this board asking about using anything other than SS or copper you will be flamed for even thinking about it.
Now go say 9 Hail Mary's and you will be forgiven.

How hot is your IC when you go to put it in the kettle - 50°C is getting to the point of too hot to touch and will cause tissue damage, so if you can pick it up with your bare hands it will not be over 50°C.
Oooh that's a good point. I didn't catch that! Also, I never claimed to be an expert on this. I just remembered something about CO and Ni and thought I would warn the OP about it. However, it appears more knowledgeable people have pointed out that it should be safe to use it as a wort chiller. Brew on!
