I have used copper flow to solder/braze some threaded studs into flat copper bar.
The copper has annealed so it's pretty soft now. How can I get it back hard? Work hardening isn't really an option as there is only a couple of inches between each stud. Being soft isn't really a massive problem, but would like to know for if I have to do any more.
