Anodizing aluminum without battery acid

Recommended Posts

It's the same process as normal sulfuric anodize, it is just creating a thin layer of aluminum oxide on the surface of the part (thicker than the natural layer that forms in air). I don't really see the reason for using this method, the sodium bisulfate is weaker in pure form, but you are using a 20% solution as opposed to the 12% sulfuric acid used in normal type II anodising. This is just as dangerous and just as hard to dispose of. The sulfuric acid solution used for anodizing is weak, so it's not terribly dangerous or hard to dispose of when need be (though you should still take caution as with anything of this nature).
