I have settled on some Phos-Copper silver brazing alloy.įrom what I can determine, the phosphor itself isnt poisonous, its supposedly used as a flux for the copper and is removed when the final product is washed. They will only sell me 250g or 500g packs which start going into the $100 - $200 range of prices, I only need 2 damn sticks not a whole pack. (repost from a different thread mistakenly posted there from a search)Īll the stuff I want to use is too damn expensive. " onclick="window.open(this.href) return false " rel="nofollow Silver brazing works especially well for joining tubular thick-walled steel pipes, provided the proper machining is done prior to joining the steel parts.” Likewise, silver brazing often requires the prior machining of parts to be joined to very close tolerances prior to joining them, to establish a joint gap distance of a few mils (thousandths of an inch) for proper capillary action during joining of parts, whereas soldering does not require gap distances that are anywhere near this small for successful joining of parts. Silver brazing is similar to soldering but higher temperatures are used and the filler metal has a significantly different composition and higher melting point than solder. Colloquially, the inaccurate terms "silver soldering" or "hard soldering" are used, to distinguish from the process of low temperature soldering that is done with solder having a melting point below 450 ☌ (800 ☏). “If silver alloy is used, brazing can be referred to as 'silver brazing'. The next bit says basically the same but is an extract from the web site shown below text. It is soft and easy to bend and melts at a fairly low temp. Plumbers solder is just a form of soft solder. It's not even silver in colour, its more of a dirty tan colour. It is hard, not soft and takes much more heat to melt. Real Silver Solder comes in very thin lengths of about a foot long and is used for soldering jewellery, rings etc. Hi Shaun, The Plumbers Solder is not "Silver Solder " at all.
