My understanding is that standard electrical soldering fluxes will not be effective on aluminum or stainless steels. Is that correct?
But are all rosin fluxes adequate for the other metals encountered in electrical work -- namely:
- Bronze (copper-tin alloy)
- Brass (copper-zinc alloy)
- Iron and non-stainless steels?
And what about the flux and solder I use to join copper water pipes: Are those equally good for electrical soldering (assuming I can work with the diameter of the solder wire)?
