Question: Have a 3/4" copper to galvanized pipe junction, has a 6" brass

electrolysis?

Other than on a water heater, when would one use an electrically isolated
union? And why?

should be dia electric union. the better question why havent ypu
replaced the galvanized ?? PEX is CHEAP and EASY TO WORK WITH!

Copper, PEX & PVC all have their place in properly designed &
installed "plumbing" systems.

I have used (& use) all three or a mix of them, depending on the
situation.

All three have their advantages & disadvantages (even copper has some
downside, besides cost).

I always favored copper (before & after the recent price spike) but
once I used PEX, my opinion changed.
I still use copper and often do the copper / PEX hybrid thing.

Don't dismiss PEX, cuz' it's plastic or "cheap"...the system has a lot
of advantages over copper, even soft copper.
