Hello, you might need a combination of steel wire for tensile strength and copper wire for low resistance to the electric current. To keep the weight low, replace copper with aluminium. Bye

(The AWG 36 wire was carefully wrapped around a couple of 3/16" bolts and carefully snugged with nuts, a poor man's fuse). As we turned up the dimmer we expected the wire to fuse but it didn't, it took the full current supplying a 100W bulb, I kid you not, that's about 0.9 amps! We got the wire from unwrapping a reed switch and checked the gauge twice by tensile strength. I invite anyone else to try the experiment. Regards Ken

They probably use Rayon. Remember that wire? Also used for speaker coil attach wires.
