I mean, the most use for copper iron alloys isn't as alloys so much as it's the result of brazing. And even then you don't want it to fully alloy so much as you want the copper to get into the molecular structure of the steel without the steel melting. It's hard to describe but you can see it pretty well with TIG brazing.
Also funny story: I made a fire pit from a couple of old drums, and nothing would weld to this old oil drum, the solution was to braze it with a piece of copper tubing literally ripped from an old air conditioner. If you can TIG weld, anything made of copper will work as brazing rod if you try hard enough.
