Can you use silver solder on refrigeration lines?
You could get away with it in drain lines, cold water fittings, and cold water lines that won’t experience large changes in pressure or temperature, but generally, you’ll want to use one that contains anywhere between 15 and 30 percent silver, known as a soft solder.
Can you solder AC refrigerant lines?
Soldering is a viable method of joining ACR tubing and components while servicing and installing refrigeration systems. However, not all types of solders can be used satisfactorily. Tin/lead and tin/antimony alloys are not normally recommended for our systems. They do not offer the required strength and ductility.
What’s the difference between soldering and brazing HVAC?
The only difference between soldering and brazing is the temperature at which each process takes place. Soldering takes place at a temperature below 840°F (450°C), and brazing occurs at a temperature above 840°F (450°C).
What is the best material to use on HVAC pipe brazing?
When brazing copper the best choice is always sil-phos. Only use silver braze on the brass and steel joints. This compound is very expensive so it is not commonly used when sil-phos can be used.
Is 95 5 solder allowed to be used in soldering refrigeration tubing?
Oatey® 95/5 Lead Free Plumbing Wire Solder is a tin-antimony wire solder designed for use in plumbing applications where frequent and extreme temperature changes and vibrations occur. It is NSF listed for potable water applications and common applications also include refrigeration lines and cooling equipment.
Is silver solder as strong as brazing?
Soldering, in addition to having a lower processing temperature, typically results in a lower-strength joint than a brazed joint. For many applications, this is suitable and even desirable. The shear strength of brazed joints typically exceeds that of soldered joints by a factor of five.
What is the melting temperature of 15% silver solder?

What temperature do you need to silver solder?
Silver Solder Melting Point When working with silver, the melting point for . 999 fine silver is 1761 degrees F and with sterling silver, it is 1640 degrees F. With solder, there are multiple flow points available because of the complexity of multi-step soldering.
Does silver solder require flux?
Silver Solder is used with a Flux, which chemically cleans the metal and keeps it clean during the Silver Soldering process. Silver Solder is also know as Silver Brazing.
Is flux required for silver solder?
These are available with either 2% or 5% Silver and are used primarily for joining Copper to Copper, where, if the metal is clean, no Flux need be used. Silver Solder can be used to join most common metals, including Mild Steel, Stainless Steel, Copper, Brass, Cast Iron and Dissimilar Metals.
At what temp does silver solder melt?
What is the difference between silver soldering and brazing?
Solder alloys with melting temperatures below 840°F are considered to be soft and any soldering done above 840°F is referred to as brazing or “hard soldering”; also called silver soldering when a silver alloy is used. As for welding the process occurs much higher up on the scale at 6000°C and up.
Do you need special flux for silver solder?
If you tried to butt the two pieces of metal together, there simply wouldn’t be enough surface area touching to achieve a strong joint. Silver Solder is used with a Flux, which chemically cleans the metal and keeps it clean during the Silver Soldering process.
