Silver brazing sheet metal. Position the metal as desired. Brazing is a technique for joining pieces of metal together by filling the join between the two metal pieces with a molten intermediary metal. When brazing with silver alloy filler metals silver soldering the alloys have liquidus temperatures above 840ºf 449ºc. Material safety data sheet 1.

Silver solder is used with a flux which chemically cleans the metal and keeps it clean during the silver soldering process. 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. Silverphos brazing filler metals silverphos silver phosphorus alloys are designed to braze copper to copper and copper to brass. Heat the joint where the two pieces of metal will meet until the joint glows.

Soldering joins materials usually metals together by melting and. The phosphorus content acts as a fluxing agent during the braze process. Brazing vs silver soldering. A silver brazing filler metal by virtue of its silver content has very little tendency to increase electrical resistance across a properly brazed joint.

For over 25 years lynch metals has been north america s largest stocking distributor of aluminum brazing sheet stainless steel other metal alloys. Brazing is distinguished from welding because it uses an intermediary material usually a copper zinc alloy to join the two metal pieces rather than melting the pieces. Brazing is only used on ferrous metals because the solder melts at 960 degrees celcius a point above the melting point of non ferrous metals.

Brazing must meet each of three criteria. If needed use clamps to secure the pieces in position. For instance brazing is the better option on a t joint with 0 005 in. Product and company identification material name phosphorus copper silver brazing filler metal.

The silver content in these alloys influence fluidity and improves the overall ductility of the brazing alloy. The intense heat of welding will likely burn through or at least warp the thin section. Apply the brazing rod to the joint while continuing to heat the metal surfaces. In most cases an overlapped joint will be stronger and braze together easier than a gapped joint.
