May work. That wire looks as a kind of litz wire, with fibers along
with the wires. But copper wires always leave a black residue. I prefer
ni-cr, because it doesn't leave anything (and because I have a lot
of wirewound resistors).
I have some brushes from an old multiple machine, that are made with
thin strips of a metal that looks as silver. They don't leave residues
too, but don't last much in a machine with bumps at the sectors.
