Brazing Copper To Steel Pipe

When brazing iron steel or other ferrous metals select one of the stay silv brazing alloys such as safety silv 45 or safety silv 56 with safety silv white brazing flux.

Brazing copper to steel pipe. But you can attach copper to steel with silver solder using a propane torch and call it whatever you like. Unlike welding were we melt the two metals together brazing or soldering use a filler material to bond the two parts together without melting them. The most commonly used brazing filler metal types used to join copper tube and fittings fall into two distinct categories. Yes copper and stainless steel can easily be soldered or brazed together using a filler material that usually contains tin and silver.

We will be brazing or silver soldering refrigerant a c lines for hvac equipment. If you re brazing with a copper phosphorous brazing rod including those with silver flux is not 100 percent mandatory when working with lines that are also copper though it s recommended. The brazing temperatures for most of the brazing alloys used to joint copper piping systems bcup and bag alloys see below are roughly between 1 150 f 621 c and 1 550 f 843 c. Technically you can either braze or solder though you cannot braze with solder or solder with brazing rods.

These alloys contain phosphorus and are self fluxing on copper. Step by step tutorial on how to braze copper pipe like a pro. Clean and flux the area to be silver brazed use a tip that produces a flame that is hot enough to heat the area without taking all day but not so hot that it is hard to control. Here are basic tips for silver brazing copper to steel or stainless steel.
