Yes, all metals, both pure (element) and alloys, can be melted;though some require large heat inputs at very high temperatures. Bycontrast the lowest melting point is of a lead-tin-antimony-bismuthmixture called "Wood's Alloy", at about 70ÂºC.
putting cells in series gives you a higher voltage but at the same current rating. putting cells in parallel gives you the same voltage but at a higher current rating. series parallel can give you both..
An electrode is used by the EDM (electro discharge machine) in actually fabricating the injection mold. An EDM uses either carbon (like pencil lead) or other material to burn the part shape into the mold. It's not part of the mold per se but used to make it.
The boilup ratio will help determine the bottom operating line of your column. Once you have both your bottom and top operating lines you can step off the number of stages (given the desired compositions at the top and bottom of your column).
Heat it up, the modulus will increase from 28 GPa to about 70-80 GPa
