Abstract
A wire electrode for use in wire-cut electrical discharge machining which can be used under a high machining tension and which produces no appreciable deposit on the workpiece it is used to machine. The wire of the invention may be made of an amorphous metal or amorphous alloy composed primarily of iron, cobalt, or copper, and coated on its surface with a layer of a metal such as zinc, magnesium, tin, lead, cadmium or alloys thereof. Alternatively, the wire electrode may be a wire of highly fine crystalline particles fabricated by super-quenching from a pure metal or an alloy of a pure metal in a molten state at a cooling rate of 10.sup.3 to 10.sup.5 .degree.C./sec in a super-quenching process such as a spinning process which forms a wire in a rotating liquid layer.
