sodium / tungsten / magnesium, aluminum, wire?

I believe that lead is toxic so perhaps not a good idea?

Most people don't eat their stereo components.

It is, but we're going to be listening, not tasting. And it would have to be insulated with something. 

Sodium wire on the other hand. Interesting stuff.  I'm still trying to find information on it, too. Any and all, just looking for "what works"

MYLAR??? What about mylar? Got um' on the moon, RIGHT???
Shorts out Highline wires all the time!!!

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.

I've seen a few crazy thing too.  I use to work for Laidlaw Environmental. Many years ago. Just about the only place you could get a job in the 70-80s. Turned out to be VERY informative. I learned EVERYTHING will kill you. simple. Question was, how fast... LOL BUT I learned how to be VERY safe around everything. Good lord we processed cyanide solvents from the Silicon Valley. The only thing we (ME) didn't fool with was radioactive, materials.  YUP I saw a few water reactive materials. 
A lot of that waste was from the Steel Mill foundries.

BUT for IC I guess sodium is out, well added lead, magnesium, alu, still on the menu, now MYLAR? I found a good source for pure Tungsten, now I have to figure is implementation.

Nickel/silver?
white/gold?
rhodium? what is that shi% anyway...Has some wonderful property apparently, it's used enough. I've never used it , Knowingly.

Just to emphasize all metals save one - lead - have directionality issues due to the deformation of the symmetrical crystal structure during manufacture. Lead has no crystal structure. Smooth sailing. Hel-loo! 🤗
