Metals for tanks

[recidivus]

So I'm here pondering some different tank ideas, and I am having a bit of issue finding some specific information. This information mostly pertains to safe-to-use metals. Polycarb/plastics are gone through in detail here, but metals not so much.

My main concerns about using metals is the effects of software on them, and their effects on software, and the overall safety of using them.

I've seen some stainless tanks posted here, so I'll assume it's okay to safely use. Do the flavours change?

Copper, aluminum, how do these hold up? Is there another (relatively cheap per tank) metal I could look into?

That's about it really, just seeing what my options are before I go trying to hunt caps and taps n whatnot.

Besides stainless and plastic,anything would require to be chromed (and even then,a genius will come in and state that chrome if chipped could kill ya)

But seriously,my tanks are all highly polished food grade stainless or chromed brass

Yea, after some thought I figured corrosion would be a big issue. Maybe gold would work, but a rat may taste like pumpkin pie. Other than that I think I'll be forgoing a full tank conversion and just make sleeves since it's a purely aesthetic preference. Plastic is also a lot easier to fix/replace if something goes wrong.

I guess I don't really need the question answered any more. Now I just have to start doing proper designs in 3D and making a parts list.

I wouldn't suggest Any Bare Metal beside a High Chromium Stailess Steel for a Tank.

Oxidation is not your Friend when it comes to tanks holding e-Liquids.

This is 100% true! Chrome is composed of Copper, Nickel, Chrome (which is actually REALLY yellow) a few acid washs and water rinses, and some copper acid. Believe me when i say that's the LAST thing you want in your efluid getting heated up. HOWEVER, that being said the odds of a GOOD Chrome plate flaking INSIDE of the tank provided nothing is scratching at it = nearly impossible.
It also depends on what type of plating was done, electro, or otherwise. Electro Plating generally as a rule of thumb is used more in applications such as this as it's known to last longer (when done right.) It's a science that requires knowledge of the guage of steel/iron, etc. that you're working with, the degrees of the Vats that you're dipping it in, the porousness of the surface area of each piece, and how many pieces that you're running at once. There are so many things that have to be taken into consideration when plating that only people that have 20++ years in the field are the ones doing applications for things that are for common usage.
How do I know what I'm talking about? Easy, my family has owned a Chrome Plating shop performing Electro-Plating for over 50 years in the DFW Area. Al's Associates Inc. & Hawk Welding (no this isn't an advertisement, it's just Proof.) I think I've got about 60 chrome stained "wife beaters" in my closet, not to mention 6+ thousand dollars worth of chrome on a tool used by MAC for Jets that's sitting on my desk (we use them as weights when we over-manufacture )
