Tungsten Copper Alloy EDM Electrode
1.What's Tungsten Copper Alloy EDM Electrode?
Tungsten copper alloy EDM electrode (tungsten copper EDM electrode) is tungsten-copper composite electrode used for Electrical Discharge Machining (EDM), suitable for machining workpieces such as cemented carbide, precision mold and superalloy. During operation, pulsed discharges occur between the electrode and the conductive workpiece; the energy from these discharges gradually erodes the material, thereby creating holes, grooves, cavities, or various complex shapes. CTIA’s tungsten copper electrodes consist of a tungsten phase and a copper phase. The tungsten enhances the electrode’s high-temperature resistance and erosion resistance, while the copper provides excellent electrical and thermal conductivity. For machining requirements such as deep holes and deep, narrow grooves, the electrodes can also feature a porous structure or internal flow channels to improve the delivery of machining fluid and the removal of machining debris.
2.Features of CTIA's Tungsten Copper Alloy EDM Electrode
(1) High-Temperature Resistance and Ablation Resistance: Tungsten has high melting point and good ablation resistance under local high temperature generated by discharge, helping reduce electrode wear and maintain machining contour.
(2) Electrical and Thermal Conductivity, Stable Electrical Discharge: Copper phase helps conduct current and diffuse heat, adapting to electrical and thermal conductivity requirements of pulse discharge machining.
(3) Customizable Structure for Smoother Chip Removal: Electrodes can feature a porous structure or internal coolant channels to deliver coolant to machining areas such as deep holes and narrow grooves, aiding in the removal of machining debris.
(4) Flexible Material and Structure for Different Machining Conditions: Tungsten-copper material composition and electrode structure can be adjusted according to machining depth, discharge parameter and heat dissipation requirement.
(5) Wide Applicability to Discharge Processes: In addition to conventional EDM, tungsten copper electrode can also be used for short electric arc milling to improve removal efficiency of materials such as titanium alloy, and for electrical discharge deposition to transfer electrode material to workpiece surface and form modified layer.
3.Applications of CTIA's Tungsten Copper Alloy EDM Electrode
(1) Mold Machining: Used for cavity machining of injection mold, die-casting mold and precision forming mold, with low electrode wear and easier maintenance of contour and detail.
(2) Deep Hole and Narrow Slot Machining: Suitable for machining deep holes, narrow slots, micro-channels, and other structures; electrodes with multiple holes or flow channels can deliver the working fluid to deep areas, allowing for smoother chip removal.
(3) Cemented Carbide Machining: Specially used for machining cemented carbide mold and wear-resistant part; EDM does not rely on cutting, so high-hardness material can also be formed smoothly.
(4) Aerospace Part Machining: Suitable for deep grooves and complex structures in titanium alloys and superalloys; it also supports short-arc milling. The electrodes are resistant to ablation, making them ideal for high-removal-rate machining.
(5) PCD Tool Machining: Used for forming, edge and dressing of Polycrystalline Diamond (PCD) tool; EDM can process conductive PCD material and complex contour.
(6) Surface Modification and Coating Deposition: Can be used for Electrical Discharge Coating (EDC) to transfer electrode material to workpiece surface and form tungsten-containing coating.
