Can You Braze Copper To Stainless Steel

Brazing in air with flux.
Can you braze copper to stainless steel. The brazing process can yield strong joints that are ductile clean and smooth. Technically you can either braze or solder though you cannot braze with solder or solder with brazing rods. 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 the right brazing rod material for the metal used in your project.
The three main methods in common use for brazing stainless steels are. Most stainless steel types with the exception of titanium or niobium stabilised grades can be brazed. You can silver solder stainless to itself or to brass or copper to make easier connections without risk of corrosion problems. Copper phosphorous brazing welding rods.
Recommended rods by metal type. But you can attach copper to steel with silver solder using a propane torch and call it whatever you like. How to braze stainless steel to copper. All i had on that day was a cutting torch but it allowed for a soft enough flame to get the job done.
Use a torch that produces a high intensity flame. Brazing stainless steels requires adequate planning as the alloys used to form joints must have properties compatible with the base metal. The recommended filler rod for brewing service is aws type bag 5 and its temperature range 1370 1550 f 743 843 c. Brazing in air with flux.
The joint will only be as strong as the silver solder itself. Brazing under reducing atmosphere. You can use any silver solder but you will need an acid based flux specifically manufactured for nickel or stainless steel. It can readily join stainless steel to itself and is an alternative to welding.
But will also cost more and requires the use of an acetylene or mapp gas torch to melt the brazing rod. However a key advantage is that many dissimilar metals can be joined to stainless steels by brazing. The higher the silver content the stronger the bond but the hotter the temperature needed to melt the filler metal. Thats a good indication that brazing material flowed where it was needed.
While brazing can provide a stronger joint the high brazing temperatures can be bad for stainless steel. Brazing copper will provide a stronger bond because of the high of silver in the brazing rod. Brazing stainless steels introduction. You can see a nice collar of silver brazing material on the head of the stainless steel bolt when its done.
