Only possible in switches and contacts.

I'm not 100% sure but I think the refrigeration fittings are silver soldered because the tin/lead solder on copper lines won't stand the pressure. Can anybody confirm this?

There is a broad range of refrigeration brazing alloys both with a small amount of silver and with none at all.

Solder on refrigeration can be silver. Heres the rub, I have seen the same silver packs on the racks at the refrigeration supply place for anything above 6 percent silver. On household refrigeration it most likely is not silver because they are joining copper to aluminum. Also there are now a lot of solders that are used exspecially on the low pressure side of the system.

You would not want to cut the system open without recovering the refrigerant, there is a $10,000 fine per incidence and a bounty for turning violaters.
