Brazing Copper To Stainless Steel

For over 40 years franklin brazing has been a leader in the heat treating industry.

Brazing copper to stainless steel.

Brazing stainless steels requires adequate planning as the alloys used to form joints must have properties compatible with the base metal. Brazing copper will provide a stronger bond because of the high of silver in the brazing rod. You can use any silver solder but you will need an acid based flux. You can purchase brazing rods with varying of silver content and either flux coated or un coated rod.

How to braze stainless steel to copper. The joint will only be as strong as the silver solder itself. Thats a good indication that brazing material flowed where it was needed. All i had on that day was a cutting torch but it allowed for a soft enough flame to get the job done.

The brazing rod should be melted by the heat of the metal pieces being joined not by direct contact with the flame of the torch. The brazing process can yield strong joints that are ductile clean and smooth. Ssf 6 silver solder and a propane torch are used to demonstrate how to join a piece of copper tubing to a piece of stainless steel tubing. Use a torch that produces a high intensity flame.

Copper phosphorous brazing welding rods. Here are basic tips for silver brazing copper to steel or stainless steel. But will also cost more and requires the use of an acetylene or mapp gas torch to melt the brazing rod. Use the right brazing rod material for the metal used in your project.

Specializing in brazing and annealing for chromium alloys such as stainless steel we treat other materials as well including carbon steel mild steel and copper. Generally welding holds stainless steel parts together best. You can silver solder stainless to itself or to brass or copper to make easier connections without risk of corrosion problems. However a key advantage is that many dissimilar metals can be joined to stainless steels by brazing.

Clean and flux the area to be silver brazed.
