Thullium, one of the rare earth metals, is relatively
air, although it will flame spectacularly and spontaneously in powder
form. ACI Alloys can supply thullium and thullium alloys.
See thullium in
"materials made" page for an idea of our capabilities--also try
searching alphabetically on each of the element symbols in
the material you are looking for.
The MSDS for thullium can be found here.
