Silver Solder Copper Sheet

The basic difference between soldering and brazing is the temperature necessary to melt the filler metal.

Silver solder copper sheet.

Copper tubing typically comes in 3 4 inch and 1 2 inch diameters. The five flux cores allow fast soldering that uses less solder and transmits less heat to the joint.

The tubes are cut with a tubing cutter and the joints are connected by soldering them together with silver solder. Silver solder also partially blends with the base metal whereas soft solder is like surface glue and sits on the copper surface and thus is a weaker joint. Today copper water pipes are soldered with lead free flux and silver alloys. As such the filler metals for soldering and brazing copper and copper alloy tube and fittings must have melting temperatures below this temperature.

Make sure the area that is covered is roughly the same as the size of your silver sheet. That said lss you did do a good soft solder demonstration. They have silver with nickel alloy sides and a copper core. Traditionally lead alloys have been used for soldering copper but these have fallen from favor in recent years due to lead poisoning concerns.

Place your silver sheet to one side and apply a small amount of flux to the top side of your copper sheet. You could do silver soldering on the job you have here but it would require tight fits and heating the copper to cherry red. A solder rod manufacturer recommends 2 silver solder rod which i assume is a phos copper rod. The melting point of copper cu alloy uns c12200 is 1 981 f 1082 c.

I ve never silver soldered 50mm cu before. What should i look out for compared to soft soldering 19mm tube. Rosin flux core lead free solder for. Copper pipes and other copper parts can be soldered using various metals with low melting points.

I m using copper but soft solder melts at too low a temperature and has been known to fail in fires.
