The one with which I am familiar is Silvaloy 355, in wire form. It is 56% silver, and contains no cadmium. It flows at 1205 degrees. I use my farm shop O/A rig with a very small welding tip and pretty low gas pressures. I don't like the work to get to flow temps too quickly, but prefer to bring it up slowly. It's more controllable for me to do it that way. Last thing I did with it was replace the guide pin on a Fox ejector. I detailed that procedure in the Gunsmithing section several years ago, AIR.
There is a special flux recommended for it, but I haven't used any for several years, and don't remember the name.
P.S. I was remembering wrong. I used a BernzOMatic propane torch to do the ejector repair job. It will easily get up to temps for Silvalloy, on small parts, as it can reach into the 2200 degree range. I read back over the procedure I posted and was reminded of that.
