Not sure about the ones used in uwave ovens, but with some magnetrons,
once they get going, the filament power has to be reduced (sometimes to
zero) because the filament is heated by the impact of accelerated
electrons banging into it.

This is a useful resource near me, stainless steel only and tend to be
larger sizes.
One man band , now internet only but no minimum order so worth bookmarking.

Last time I talked to him, late 2010, he mentioned he was starting a range
of "classic car" nuts and bolts , whatever that is, cannot find mention on
his site though

In the UK, modern cars use metric threads. Ones from about after WW2 to
the '80s mainly UNF and UNC. Pre WW2 BSW and BSF. BA was common for
electrical stuff.

A classic car is really just any which isn't recent and not defined under
the strict headings of vintage etc. It isn't restricted to any make - just
over 20 years old. Although that age isn't agreed by everyone.

...alternate..vacuum sputter deposit for any thickness you want; control
can be as good as 1/10 wavelength of light (pick your favorite color).
...another alternate..perhaps gold film?

I've always wondered (and dreamed) of a speaker cabinet made of granite or
soapstone. With the right drivers, I'll bet they'd sound great.
