Corrosion resistance of anodized aluminum to deionzed water



(-----) 2006

Deionized water is hungry for ions. Are anodized aluminum vessels suitable for storing DI water?

DI water can vary from 50 Kohm to 18 meg ohm. Teflon is the best answer for 18 Meg ohm water. Glass is suitable for 1-2 meg ohm water. Selected polyethylene and polypropylene is suitable for a good range in between. Aluminum is not a great idea for any level, but could get by for short applications where leaching was not important.

If you just want to use tanks that you have on hand (I made a leap... fuel tanks?) You'll have to coat the inside with a good waterproof epoxy, urethane, or teflon. If you can do that the aluminum will be acceptable. Don't expect long life from aluminum tanks, DI water will make them brittle in a few weeks and they will eventually fail, probably in an impressive way (big hole all at once!)
