Tungsten Copper EDM and ECM
Tungsten copper bimetals are used most economically as electrodes in Electrical Discharge Machining (EDM) & Electro-Chemical Machining (ECM). The spark erosion characteristics & good electron emission characteristics of these sintered products make them excellent EDM electrode materials. They have excellent wear resistance, good material removal rates & the ability to retain good detail. They are particularly suited for machining Tungsten Carbides as other electrode materials may be inadequate. Tungsten Copper is used for ECM electrodes because it conducts high current & resists deformation & abrasion from the high velocity movement of the electrolyte. Tungsten copper alloy is manufactured by the press, sinter, and infiltrate process; adhering to strict quality checks every step of the way. You can rely on the quality of our tungsten composites to provide consistent, homogeneous materials that yield high and even burning rates.
EDM is a machining method primarily used for hard metals or those that would be impossible to machine with traditional techniques. One critical limitation, however, is that EDM only works with materials that are electrically conductive. EDM or Electrical Discharge Machining, is especially well-suited for cutting intricate contours or delicate cavities that would be difficult to produce with a grinder, an end mill or other cutting tools. Metals that can be machined with EDM include hastalloy, hardened tool-steel, titanium, carbide, inconel and kovar.
EDM is sometimes called "spark machining" because it removes metal by producing a rapid series of repetitive electrical discharges. These electrical discharges are passed between an electrode and the piece of metal being machined. The small amount of material that is removed from the work piece is flushed away with a continuously flowing fluid. The repetitive discharges create a set of successively deeper craters in the work piece until the final shape is produced.
