My Chrysler has a bad alloy wheel. $373 at the dealer.
I found one at an auto wrecking yard for $60.

Junkyard wheels are okay, but they need to be checked carefully
before reuse. You always have the tire shop put the wheel on the
balancer without a tire and spin it to check that it is not bent in
either direction. And if there are any questions, take the wheel to a
machine shop for a Magnaflux and/or dye test to check for cracks.
Once Aluminum is bent past it's working points, it develops cracks
easily and they will spread as you keep flexing it. Someone could
have whacked that junkyard wheel against a curb in the recent past,
the wheel may look great now but fail after some use.

The tire store was nice to tell me that there's a number
on the back of the wheel that identifies it.

There is an ID string stamped on or cast into the wheel that has the
diameter and width, code letter(s) for the lug type and offset, and a
manufacturer identification - like "14x7 JJ TOYOTA". They might also
have a date code or plant code so they can trace back faulty wheels,
but I haven't looked lately.
If it's the right size and offset, and the right bolt pattern, it
should fit. But sometimes the only way to be sure is to mount the
wheel and make sure it clears the brake drum/rotor/caliper.

I haven't seen these. I would like to fix the old wheel
and keep it around just in case, if it's cost effective.

Anyone who repairs aluminum wheels has to REALLY know what they are
doing, because doing good structural welds on aluminum is very
difficult. And wheels use casting or forging grades of aluminum
alloys that are even harder to weld than the usual extrusion or sheet
goods that they use for a bass boat.
This isn't something to taker to your friend with an old Lincoln
AC/DC Tombstone buzzbox and zap it back together. It takes a master
welder with thousands of hours experience, and several grand invested
in TIG welding equipment and supplies.
Then they have to have a big oven to preheat the whole wheel before
welding, and pop it back into the oven for a controlled cooling, or
the differential shrinkage can pop the crack right back open...
And you have to get the alloy of the filler rod right, or the repair
will show after refinishing the wheel, and the wrong filler will fail
again. I know enough about welding to know what I /don't/ know, and
there's no WAY I would attempt that one.
