You can purchase brazing rods with varying of silver content and either flux coated or un coated rod.

Copper phosphorous brazing welding rods. 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. I feel like you didn t actually read this article. 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. Thats a good indication that brazing material flowed where it was needed. How to braze stainless steel to copper. 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.
