That I really do not know. I've run across some heavier ground wire off of electric poles that has been bent enough to be worked hardened. At the bottom of the pole it is wound into a spiral before the pole is set into the ground (called a butt wrap) but as for common products... no clue. Welding tips for a MIG welder, maybe?
