I can get you a piece of hard-drawn, work-hardened, oxygen-free, high-copper, but you would need to send it back quickly. Next Wed. is my last day at work, have to leave for uni. Two-day or overnight shipping shouldn't be too expensive for a small piece. Any size preference? Also, what do you think would be the best way to get maximum work hardening? I can use a mill, hydraulic press.... but since the piece is hard drawn, it should already be fairly hard. Or I could just smack it with a hammer a couple dozen times ;).
