A method for electroforming and electrodischarge machining uses, an electrically conductive thermoplastic wax composition which can act as an electrode on which a metal article may be electroformed and as an electrode mount for the metal article to be electrodischarge machined. The electrically conductive thermoplastic wax composition comprises a thermoplastic wax material and very small spherical particles the surface of which have been treated to make them electrically conductive. The electrically conductive thermoplastic wax composition is easily separated from the metal articles formed by electroforming or electrodischarge machining (EDM) by heating to melting temperature and/or by use of a suitable solvent for the thermoplastic wax. In this way, the composition may readily be recovered for repeated reuse in another electroforming or EDM process, and accurately formed finished articles having intricate shapes and close tolerances can be produced. In a preferred embodiment, the spherical particles are silver coated solid glass microspheres comprising 60 to 75 percent, by weight, of the overall thermoplastic wax composition.
