steponmebbbboom Posted April 5, 2008 Share Posted April 5, 2008 i have caught wind of a story that any traces of copper in a fire will make forge welding difficult if not impossible. is there any truth to this? Or can copper and iron be forged in the same fire without problems? Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted April 7, 2008 Share Posted April 7, 2008 The big problem is that copper can merge into the steal causing intergrannular failure of the metal. This is a problem at higher heats. Quote Link to comment Share on other sites More sharing options...
Rich Hale Posted April 7, 2008 Share Posted April 7, 2008 Every student at the horseshoing school was taught to do a copper brazing project,,in the same coal forge that had been used for thirty years, and the same forges were used for forge welding. Not a Problem. Quote Link to comment Share on other sites More sharing options...

matt87 Posted April 8, 2008 Share Posted April 8, 2008 That's not technically welding, it's brazing with copper. (Pennies are no longer made of copper.) Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted April 8, 2008 Share Posted April 8, 2008 US pennies are copper coated zinc since around 1984; older ones are mainly copper but not pure copper. I do not know about Canadian, UK, HongKong, Australian, etc pennies The zinc ones make nice item to juice up a brass pour that has been burning off it's zinc right before a pour though.

Walking Dog Posted April 9, 2008 Share Posted April 9, 2008 Copper electrical wire is a good source of material for forge brazing - it works well for me, both with the torch and in the forge. I also forge weld in the same forge. Flux with borax. Quote Link to comment Share on other sites More sharing options...
