Can You Braze Steel To Copper

It s excellently written and is clear about the differences between soldering and brazing.

Can you braze steel to copper.

How to braze stainless steel to copper. Most silver solders can be categorised by their silver content. Use a torch that produces a high intensity flame. The higher the silver content the stronger the bond but the hotter the temperature needed to melt the filler metal.

You can see a nice collar of silver brazing material on the head of the stainless steel bolt when its done. All i had on that day was a cutting torch but it allowed for a soft enough flame to get the job done. Recommended rods by metal type. But will also cost more and requires the use of an acetylene or mapp gas torch to melt the brazing rod.

But you can attach copper to steel with silver solder using a propane torch and call it whatever you like. You can use silicon bronze filler wire and a tig welder to weld steel to copper most easily while maintaining as strong of a bond as possible between the two metals. Work at your own risk. Brazing copper will provide a stronger bond because of the high of silver in the brazing rod.

If you re using silver solder that is solder with 45 percent silver or higher to connect copper to steel you must always use an acid based flux. 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. C2 is a multi purpose silicon bronze brazing rod that s suited to most general purpose brazing on metals including steel copper cast iron and dissimilar metals. You can purchase brazing rods with varying of silver content and either flux coated or un coated rod.

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. You can braze cast iron to steel where cast iron has a melting temp of 2150f and bronze the filler material has a melting point of 1750f. The best option for welding steel to copper is actually a brazing technique since the melting points of steel and silicon bronze the required filler metal are so disparate. Technically you can either braze or solder though you cannot braze with solder or solder with brazing rods.

C2 braze is brass coloured and typically melts at around 875 c. I feel like you didn t actually read this article.
