In fusor mode, ion collisions will liberate electrons from the grid, requiring a supply of current. The work function of the material you choose will have some impact on how much current you will need to supply, but I don’t think you need to concern yourself with that too much. I would just try something cheap and workable.

In Polywell mode you will have to worry about drawing the current off, as you will have a higher (hopefully!) population of electrons. In this case, secondary electron emission can be a serious factor in terms of efficiency and so you might care a bit more when it comes to this part.

http://www.mcmaster.com/#55-fc-0-welding-wire/=1kkmhy

I’m guessing ER 308L— Solid— For welding Types 301, 302, 303, 304, 304L, 308, 308L, 312, and 347 stainless steel. Resistant to corrosion, impact, and abrasion.

Fusors are very forgiving in terms of tolerance for grid warping, since radial ion convergence isn’t really that critical at ~mTorr. Unless aesthetics is one of your main concerns, there is no need to spend $100(s) getting a pretty, symmetric grid.

I’m guessing I could use their process with thicker grid wires.
