Wire diameter 0.03 mm to 0.10 mm
SP Wire is a hybrid double-layer electrode wire consisting of a high strength special steel wire core and a copper alloy outer layer with excellent electrical properties, having similar advantages of both tungsten wires and brass wires.
SP Wire, produced by bringing together the fine wire technology and the plating technology developed by us over many years, will meet your needs in all respects with its superior properties such as high tensile strength, electrical discharge characteristic, processing performance, mechanical/electrical properties, cost performance, etc.
This high-performance electrode wire replaces conventional tungsten wires or brass wires in the precision and micro-cutting field.
The hybrid double-layer structure provides advantages of both tungsten wires and brass wires to have tensile strength almost equivalent to tungsten wires in the practical use, and to have higher electrical discharge characteristic than brass wires. Further, surface hardness and roughness are far much lower than those of tungsten wires, and those advantages make the SP Wire less abrasive to rollers and pins in the wire running system of EDM.
SP Wire is sure to outshine tungsten wires in the ultra-precision cutting field, and also enables a more precise cutting by its high tension in the brass wire territory. The same corner R could be cut with a wire with diameter one size thicker, because of the narrower cutting widths by SP Wire, thus the cutting speed is far much increased with SP Wire.
Further more, numbers of cutting operations in cutting process can be far reduced with SP Wire in the field of fine wire below 0.1mm. Together with features described above, SP Wire enables to shorten cutting time, reduce costs, and shorten delivery lead time.
