Heat the joint where the two pieces of metal will meet until the joint glows.

Silver brazing sheet metal.

Product and company identification material name phosphorus copper silver brazing filler metal. Brazing vs silver soldering. The silver content in these alloys influence fluidity and improves the overall ductility of the brazing alloy. Apply the brazing rod to the joint while continuing to heat the metal surfaces.

There are many ways to heat the joint automatically many forms of brazing filler metal and many ways to deposit them so that a brazing operation can easily be automated for almost any level of production. When brazing with silver alloy filler metals silver soldering the alloys have liquidus temperatures above 840ºf 449ºc. Silver solder is also know as silver brazing. The phosphorus content acts as a fluxing agent during the braze process.

Sheet metal bonded to 0 5 in. Silverphos brazing filler metals silverphos silver phosphorus alloys are designed to braze copper to copper and copper to brass. For over 25 years lynch metals has been north america s largest stocking distributor of aluminum brazing sheet stainless steel other metal alloys. The intense heat of welding will likely burn through or at least warp the thin section.

But you can further insure minimum resistance by using a close joint clearance to keep the layer of filler metal as thin as possible. Brazing must meet each of three criteria. Soldering joins materials usually metals together by melting and. Silver solder is used with a flux which chemically cleans the metal and keeps it clean during the silver soldering process.

If needed use clamps to secure the pieces in position. A silver brazing filler metal by virtue of its silver content has very little tendency to increase electrical resistance across a properly brazed joint.
