REQ: Filler metal for TIG brazing stainless steel to copper?

Silicon Bronze works very well.

Do NOT use Sil-phos-bronze or Phos-bronze, The phosphorus can lead to cracking on steel alloys.

Silicon Bronze also goes by the name Everdur.

Thank you.

Based on your previous posts I had already purchased a roll of silicon bronze MIG wire.

Just out of curiosity, would nickel silver work? Would a CuAg (AgCu?) alloy work?

Thanks for all of your posts!

I have not had good luck with Silver alloys in a TIG arc. The silver boils out at too low of a temp, making heat control very tricky. Nickel alloys can work, but tend to crack while cooling, unless you do a preheat of the area and a slow cool.
