I have done some work in a wire drawing plant and they would receive undrawn wire on bobbins that stood vertically. That wire was at least 1/2"/13mm thick. I want to get my hands on some of that. Or even just some drawn solid bare copper wire larger than 1awg. I can't seem to find any hint of its existence on the internet, even from alibaba. Maybe I'm not googling the right words. Any ideas?
