Silver Brazing Sheet Metal

Brazing vs silver soldering.

Silver brazing sheet metal.

If needed use clamps to secure the pieces in position. 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. 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.

Product and company identification material name phosphorus copper silver brazing filler metal. Brazing must meet each of three criteria. In most cases an overlapped joint will be stronger and braze together easier than a gapped joint. Heat the joint where the two pieces of metal will meet until the joint glows.

Sheet metal bonded to 0 5 in. But you can further insure minimum resistance by using a close joint clearance to keep the layer of filler metal as thin as possible. Position the metal as desired. A silver brazing filler metal by virtue of its silver content has very little tendency to increase electrical resistance across a properly brazed joint.

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. Silverphos brazing filler metals silverphos silver phosphorus alloys are designed to braze copper to copper and copper to brass. When brazing with silver alloy filler metals silver soldering the alloys have liquidus temperatures above 840ºf 449ºc. Silver solder is used with a flux which chemically cleans the metal and keeps it clean during the silver soldering process.

Soldering joins materials usually metals together by melting and. Home contact blog 888 272 9464 908 686 8401. The silver content in these alloys influence fluidity and improves the overall ductility of the brazing alloy. For instance brazing is the better option on a t joint with 0 005 in.

Material safety data sheet 1. The intense heat of welding will likely burn through or at least warp the thin section. Silver solder is also know as silver brazing. Apply the brazing rod to the joint while continuing to heat the metal surfaces.
