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.

Briefly, can you silver solder AC lines?

Never use solder with lead in an HVAC application. 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.

In no way, what is the best flux for silver soldering? Batterns and Handy Flux are the top choices. Boric acid and water is also used. Batterns Self-Pickling Flux is used for hard soldering (solder that melts at a high temperature) of gold, silver, and platinum. It can be diluted with distilled water if it is too thick.

Additional, what percentage of silver is in silver solder?


Can you solder HVAC 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.

Can you use silver solder on copper?

A simple way of soldering together a piece of copper and a piece of silver is to use a technique called sweat soldering. ... Now, with a small amount of easy silver solder coated in flux and placed at the very end of some fine tweezers, you can begin to heat it with your hand torch.

Is Mapp gas hot enough to braze?

Genuine MAPP gas can be used in combination with oxygen for heating, soldering, brazing and even welding because of its high flame temperature of 2925 °C (5300 °F) in oxygen. The hydrogen infuses into the molten steel and renders the welds brittle.

How strong is a silver solder joint?

The bulk tensile strength of silver braze alloys is 40,000-70,000 psi. When brazing copper-based alloys, failure will occur in the copper or brass.

Can I use borax as flux?

Flux. A mixture of borax and ammonium chloride is used as a flux when welding iron and steel. It lowers the melting point of the unwanted iron oxide (scale), allowing it to run off. ... Borax is often used as a flux for forge welding.

How do you make silver flux?

  • What is the difference between easy medium and hard silver solder?

    The solder metal is of a lower melting temperature than the two pieces it's fusing. ... Hard solder melts at a high temperature, medium melts at a lower temperature, easy melts at an even lower temperature. Multiple solder joints in a piece of jewelry require multiple types of solder.

    Does silver solder go bad?

    The metal itself can also oxidize but it is so slow it is unlikely to matter and also depends on the type of metals used. ...
