that's what I thought. I couldn't find much info on the interwebs. Thanks.I'm reasonably sure all brass will work harden (in fact I think all metals will work harden if my understanding is correct). You can always re-anneal as you go though, it's simple to do for brass.
ok, so here is my understanding, and I am probably wrong as I don't have formal training.I was always under the impression that to anneal brass and copper
you heated and then quenched in cold water.
Finally, Crueby got it right!When annealing brass/copper, its the heat that matters, all the quenching does is let you get back to work faster. It does not matter when annealing brass/copper if you quench or just let it air cool.
