i have to disagree, i still maintain that tungsten carbide is hands down
the best electrode material there is. anyone that takes the initiative
to try it will agree if they've tried many different materials.
absolutely no wear, good conductivity, great sinking ability and super
cheap all adds up to far and above all else.
