Even aluminum requires a machine that costs like $50k.

No (but that's beside the point). Brass/bronze is also much, much less
conductive than pure copper. An inductor estimating program I have places
even red brass below aluminum in conductivity, and yellow brass and
phosphor
bronze between zinc and tin.

Likely to be worthless when finished because it would be too soft, and the
thread could be easily screwed up with solder, too. I'd say that's a long
