It's now called lead free, but still bends the same, and just about weights the same. You won't find it at Wally World, but most good fly tying shops have it.
You could also try to track down old fashion lead wool at an old fashion plumber supply house. It's like steel wool, but made from very fine lead thread, just a pain to pull apart and separate, and you really don't end up with very long strands, a couple of inches long at the most. Also fine copper wire, run it through a flame to remove the varnish, and anneal it, becomes just as flexible as lead/fuse wire.
Am I the only one old enough to remember replacing fuse wire and fusible links in cartridge fuses?
