Can you braze steel to copper. Work at your own risk. But will also cost more and requires the use of an acetylene or mapp gas torch to melt the brazing rod. 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. Technically you can either braze or solder though you cannot braze with solder or solder with brazing rods.

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 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 braze is brass coloured and typically melts at around 875 c.

How to braze stainless steel to copper. 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. I feel like you didn t actually read this article.
