Brazing copper is suitable for joining copper alloys but it's important to be able to identify which filler metals to use. Learn more about copper brazing here.
How to braze copper. Brazing is done by heating the copper, then running a layer of constantan (a type of metal with high thermal conductivity and low electrical resistivity) on top. If you line up the two pieces correctly, they will fuse when heated to 250°C.
Brazing copper is a process of joining two pieces of copper or copper alloys together using a filler metal that has a lower melting point than the base metal. The filler metal is melted and then flows into the joint, creating a strong and permanent bond between the two pieces of metal.

This video describes how to properly braze copper tube. Copper Development Association's Piping Specialist, Harold Moret, explains when brazing is appropriat...
Brazing copper is the most common method of joining copper tubes with the use of a socket type. Even though copper brazing is relatively easy to master and perform, there are a couple of things that could affect the properties of the brazed joint.
Figure 2 – Example of a brazed copper-silver joint. (Note that no filler metal was used; the alloy Ag72Cu28 is formed by diffusion during the brazing process.) Cu Ag
Brazing copper is a common method and reliable alternative to traditional soldering. It is a versatile way to join copper pipes, copper fittings, and tubes. Brazed joints provide stronger joint than conventional solder joints as it creates a solid, inseparable bond between the parts and increases the joint strength.
Torch brazing copper tubing is one of the most common–but widely misunderstood–joining processes. It's possible to make sound joints that are just as strong as the copper tube, easier to braze, and less expensive to produce. But first you have to know basic brazing concepts, including joint design, filler metal behavior, and metallurgy.
ng or brazing. These fittings are made from the same alloy as the copper tube, and when joined to copper tube by brazing with a phosphorous-containing filler metal can be joined without the use o. brazing flux. Many specialty fittings, valves, etc. used in HVACR systems are made from other copper alloys, like br.
