sodium / tungsten / magnesium, aluminum, wire?

We used to have a press for making sodium wire, it was used to dry various solvents. It’s pretty soft stuff but worse than that is the fire risk, it’s a trifle combustable itself and generates hydrogen if you get it wet and also enough heat to potentially ignite the hydrogen though not as much a potassium would. Magnesium is a bit less reactive, stable enough to make wheels from for instance, at least when alloyed, but these have a limited life. In wire form you have a relatively large surface area so its reactivity matters more, the bright light it emits when burning is quite impressive.
