[TheForge] tungsten for punches?

[Ries Niemi]

Considering how easy it is to snap a Tig ELECTRODE (not a "rod"- generally speaking, "rod" would refer to a filler rod of base metal, not a tungsten electrode), I think it wouldnt work.
Tungsten is hard, but brittle. It is alloyed, or distributed in matrixes, to make hard cutting edges, but I really doubt it would be very good for an impact tool.

You might consider trying some of the depleted uranium, though- the Israeli blacksmiths have been said to have forged some it- and since its tank penetrating ammo, it is better suited to beating on.

but hey, try it and see- and 1/8" tungsten electrode is only a few bucks, buy one and see how it works.
