Hi This is my 2nd request for info.on soldering pot metal. Pot metal
or zinc die cast metal is in question. I was sent a sample of solder a
few years ago that soldered this type of metal. The solder was like a
lead solder with special flux. I misplaced the mfg. info. but I know
that there is such a product. Help!!!

I have a book PRINCIPLES OF CENTRIFUGAL RUBBER MOLD CASTING by Jerome
A. Gonicberg and Marshall L. Ritch published by The A. J. Oster
Company, a casting company. The book covers moldmaking and casting of
pot metals. They have a listing for consulting/troubleshooting. You
might write to them and see if they can help you or direct you to
someone who can.

By pot metal, I assume you’re talking about a zinc-based alloy.
Check the Rio Grande catalog. They have solder which will likely do
the trick. I bought some from Rio a couple of years back and have
soldered “white metal” (aka pot metal, aka white metal etc) with it
quite handily. Just don’t let your parent metal get too hot – and
this isn’t very hot at all – just work slowly up to your soldering
temp. with a small flame. If too aggressive with the heat you get the
questionable delight of watching a chunck of what you’re trying to fix
just fall away in a silvery blob.

Try Tix Solder. It should work well. I have used it a number of
times on pot metal.
