Thread: Stainless Steel vs. Aluminum

    Default Stainless Steel vs. Aluminum

    Is it better to use pure Aluminum plates or Stainless Steel plates in a HHO electrolyzer??

    If your using NaOH or KOH aluminum will last a day or two.
    Which stainless steel are you referring to?

    It seems that the 316 or 316L grade stainless is preferred. I would want to use only tap water or tap water with baking soda for the dielectric.

    Why do you only want to use tapwater? Depending on the quality of your tapwater of course...you may end up with some brown goooey stuff, not worth the maintenance!

    Especially when distilled water is like 72 cents a gallon at the store

    I want to use aluminum instead of stainless steel because of cost and ease of fabrication. The only issue I can see is the selection of dielectric. Tap water is the most convenient, however if adding a small amount of other material helps, thats great. As long as it does not adversely affect the electrolyzer.

    None of your issues effect the real world reality of making a good reliable cell. Cost, Ease of fabrication, convenience are all parameters which you have created I could sit here all day and predicate to you about how many other people have gone your route and failed, but it appears you are set in your ways. I wish you the best of luck and am eager to learn from you if indeed you find any advantages whatsoever in your method. I promise I will eb the first on bended knee with hat in hand!

    I may end up using SS. I don't know yet. Pure aluminum does not rust but it does oxidize a bit. SS contains a bit of iron and it rusts. SS does not seem to oxidize as much though. What do you think is the best plate material and why?

    There is alot of information about aluminum in this thread. http://www.hhoforums.com/showthread....light=aluminum
