ABSTRACT:
A wire electrode for wire-cut electrical discharge machining includes a wire composed of a core made of one of an amorphous pure metal and an amorphous alloy and a thin crystalline layer serving as a surface of the core. The wire may be coated on its surface with a layer of a material of high electrical conductivity. The amorphous alloy may be Cu-based, Fe-based, or Co-based. The use of an amorphous pure metal or alloy yields a wire electrode of much greater tensile strength than previous wire electrodes, enabling a higher machining speed.
