I can provide quantites of Tungsten wire for research purposes, such as fusor grid construction.
Also, has anyone thought about using W wire with 25% Rhenium? Rhenium is used as an addition to Tungsten or Molydenum in x-ray targets. The stuff is expensive, but there is usable scrap out there.
As for Tantalum wire for the grid, I would expect that it would embrittle rapidly because it is a good getter, especially in a Hydrogen atmosphere.
But then again, I hear they use Ta sheet in ion sources.

The Martin Alloys Corporation specializes in the recycling of Tungsten and Tantalum scrap, along with other exotic metals.
