I beleive the original pins were tungsten wire in some printheads. The
stuff certainly behaves like tungsten...
I wouldn't be surprised. Tungstan has a lot of properties that would
make it usefull in print heads; very hard so less wear, heavy weight for
inertia, and it withstands high tempertures well. But I'll be the
manufacturers hate it, it's hard to machine and expensive.

If you
need to, use tungsten wire for the print
hammer pins themselves. Also replacements would
not rust.
If you can't find the right size wire, try piano wire (from a hobby
shop) or drill rod (industrial suppliers). Drill rod is annealed (soft) but
