Can you braze copper to stainless steel?

When joining two metal components, knowing what materials can be used in the process is important. While welding and soldering are common processes for joining metals, brazing is a great option for copper and stainless steel. Keep reading to learn more about this type of joining process and why it is effective for these two materials.

What is Brazing?

Brazing is a process that uses heat and a filler material (usually an alloy) to join two metals together. The use of heat melts the filler material, which then flows into the gap between the two metals, creating a strong bond when cooled. It is important to note that brazing can only be used on materials with similar melting points; if both pieces of metal have different melting points, they cannot be joined using this method.

Can You Braze Copper and Stainless Steel?

The short answer is yes! As long as both metals have similar melting points, they can be joined using brazing. In this case, copper and stainless steel both have relatively high melting points but are still close enough in temperature to be successfully joined with this method. Additionally, because the filler material has a higher melting point than copper or stainless steel, it creates an even stronger bond between the two materials.

In order for brazing to work effectively on copper and stainless steel, you must use the proper tools for the job. For example, you’ll need an oxy-acetylene welder or torch to create enough heat for the filler material to melt properly. Additionally, you’ll need flux paste to prevent oxidation while you work – without this step, your joint will not hold up over time. Finally, you’ll need a good quality alloy such as silver solder or brass alloy wire to ensure that your joint is strong enough for whatever purpose you intend it for.


Brazing copper and stainless steel together create strong joints between dissimilar metals with similar melting points. In order to get the best results from your project, make sure that you are using quality equipment such as an oxy-acetylene welder or torch along with flux paste and an appropriate alloy wire or solder material. With these tools and the proper technique, you should have no trouble brazing together these two metallic materials!
