Silver solder for hvac. Silver solder a goodman air conditioning unitAmazon link to Great products that every DIYer and Handyman should know aboutSwitch and Receptacle Spacers htt. This makes them suitable for most residential HVAC connections. During brazing copper is heated to over 1300F.
At this temperature copper softens with resultant weakening of the tube adjacent to the brazed joint. The low operating temperature of tinsilver solder does not overheat the tube so. The best term to call it is a brazing alloy I try to remember it but I often find myself calling it silver solder.
The most common rods used for typical HVAC brazing are 0 5 and 15 with several other levels mixed in there. The percentage is the percentage of silver content in the rod.

Silver- Bearing Solder Joint R410a filter Drier Silver-Bearing Solder Creates a Stronger Joint. Copper Pipe fittings sealed using Silver-bearing Solder are stronger than a joint thats been brazed together. The burst rate of a Staybrite fitting is around 3800 PSI.
A brazed fitting burst rate is only 1800 PSI. Both create strongly bonded fittings. Silver Solder relies on surface area and a tight joint for strength.
You would not use Silver Solder for an edge to edge joint. An overlapping joint is ideal. So the short answer is YES it would be strong enough but only if the right type of joint is used.
Silver Soldering Stainless is tricky DO NOT let the Stainless Steel discolour in the heat. Seeing silver solder melts at a much higher temperature youll be needing more heat than your typical soldered joint. Brazing smaller pipes is possible with a small propane torch but larger pipes such as 1 and up require more heat therefore its recommended to use an oxyacetylene system with an appropriate torch seeing silver solder melts at a higher temperature than normal solder.
Harris is very confident in their solder and even claims that overall joint strength is improved by soldering because the high heat of brazing anneals the tube making it weaker. Solder can be nice in some situations if youre working in a certain area or with a certain component where you want to keep the heat down. For water pipes all solder is lead free now and it works better than the solder containing lead.
In newer units low temperature soldering has been eliminated by all manufacturers in favor of high temperature silver brazing. You will have occasion to solder water pipes. Rosin Flux-Core Lead-Free Solder for HVAC Applications.
