Re: Aluminium as Electrode

One problem with aluminum as an electrode is oxidation. I have used aluminum before, and the result can vary. For DC power, it aluminum is used for the positive electrode (anode) it oxidizes quickly forming an insulating surface that stops further current flow. This is basically the anodizing process, which is normally done in an acid bath. I suspect your results will not be good, but it might be worth trying an experiment. Just be careful, do not leave the thing unattended, and keep the amounts of material small so if you get a thermite fire or something like that you do not burn down the shop.
