Yes I've found it's very frustrating looking for "genuinely zero lead" brass and bronze. Almost all scrap has lead in it to some degree, and even new metal often has a trace.

Remove about 82% of lead from bronze using this one weird trick!

I was hoping for something involving a particle accelerator and making gold.

Neat, this dovetails with another interest of mine, pottery. NaF is "sodium feldspar" and Ca-Si compounds are "wollastonite" among others. Both useful as fluxes in metal casting, in addition to their pottery uses.

Lead free brass is still 0.2% or less. Mitsubishi makes it. "Eco brass".

I'm not sure it's brass anymore without the lead.

Why does it seem that the better a material works the worse it is for humans.
