<p>[QUOTE="Johndoe2000$, post: 2665199, member: 82085"]Hello Dan, having plenty of experience working with strip ( flat ) metals, as well as round ( wire ) of all types of alloys, I know that with each reduction, or pass, the material gets harder, ( gains tensile strength ) So I was wondering if you had/ have to annual ( heat at high temp to soften ) the material before punching out the planchets, or before striking the medals ? Or does the silver remain soft enough even after the C.W.H. (cold work hardening ) or do you need the extra hardness to help with the striking ? If you don't want to give away some of your trade secrets I understand, only curious due to my background. And to let you know that I am available and willing to relocate to work for you. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie2" alt=";)" unselectable="on" unselectable="on" /><img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie6" alt=":cool:" unselectable="on" unselectable="on" /></p><p>P.S. it is rare for me to even have an opportunity to discuss such a topic, as not too many people would even know what I'm talking about.
