Obviously this website is dedicated to welding, but I'm hoping someone knows enough to inform me on this brazing issue.I'm looking to braze a thin strip of 0.015" O1 steel, 0.25" wide, to a 0.125" copper C101 bar, 0.25" in width.Anyone know if this would work well?Thank in advance for your time.
Reply:clearly the challenge will be to get the copper hot enough to melt the brazing rod without vaporizing that tiny piece of steel.you might have to get the copper tinned first  and then try to get the steel to tie in there.let us know...
Reply:Hey axi0m,One of the companies I retired from did hundreds of thousands of small, thin assemblies like that. We furnace brazed them. The other spectrum was when I ran the weld dept & we brazed with the parts pre-fluxed, sil-sol strip sandwiched between steel & copper, & carbon to carbon heating with the assembly between the carbons. Maybe that will give you something to contemplate.DennyComplete Welding/Machine/Fab.

Reply:If you try to braze them without a fixture, the difference in expansion coefficient is going to make the finished part curl as they cool.  The copper will be soft, so it may be possible to straighten them.  If you intend to quench them, I think you will need a fixture.
