Re: Solder, wither art thou?

Depends on the salesperson and their client base. Nominally, "silver solder" is for brazing and has a rather high melting point and needs a torch for working. Now, in electronics, the terminology that has been used is "silver bearing solder" and _that_ stuff normally has only 2% silver, but there has been some 2.5% and 3% alloys as well. The solder inside the old tube Tektronix scopes was "silver bearing solder" and had 2% silver; the idea was to prevent leaching of the silver from the ceramic "tiepoints". Sorta like good old Savbit which had 2% copper to prevent leaching of the copper in soldering iron tips ("bits").

I think so. I just bought some for 'soft soldering' to stainless steel. I tried to buy the eutectic 157 brand I used as a Grad student... $150 a pound and 5 pound minimum order.. ouch! I found the same stuff sold by Stay Brite at a fraction of the cost. (The stainless steel flux is nasty stuff.)

It is one of the alloys called that sometimes. It is not one of the=20 alloys called that normally. "Canonical" silver solders have notably=20 higher melting points and higher mechanical strengths.
