Tungsten Copper Electrode Wheel
1. What's Tungsten Copper Electrode Wheel?
Tungsten copper electrode wheel is a specially shaped conductive electrode designed for Electrical Discharge Machining (EDM) and Resistance Seam Welding (RSW). CTIA's tungsten copper electrode wheel combines high electrical and thermal conductivity with superior hardness and wear resistance to serve two distinct functions: delivering pulse currents for EDM shaping and grinding of Polycrystalline Diamond (PCD) tools, or conducting welding currents via rolling contact to produce continuous or intermittent seams on metal workpieces.
2. Characteristics of CTIA's Tungsten Copper Electrode Wheel
(1) High-Temperature Resistance and Arc Erosion Resistance: Tungsten has high melting point, improving electrode wheel resistance to erosion under high-temperature discharge conditions. This makes it suitable for EDM and resistance welding applications.
(2) Good Wear Resistance and Low Wear Rate: Tungsten copper has relatively high hardness, helping reduce wear on the working surface and maintain electrode wheel shape and dimensions. CuW75 has hardness of approximately 195 HB or higher, while CuW80 is approximately 220 HB or higher.
(3) Good Electrical and Thermal Conductivity: Copper helps conduct current and dissipate heat. CuW75 has electrical conductivity of approximately 38% IACS or higher, while CuW80 is approximately 34% IACS or higher. In general, higher tungsten content increases hardness but reduces electrical conductivity.
(4) Diverse Shapes and Strong Equipment Adaptability: Available in disc, wheel, and other customized shapes, tailored to equipment interfaces, mounting holes, and working surface dimensions.
(5) Diverse Materials and Flexible Selection: Common materials include CuW70, CuW75, and CuW80; EDM grades are chosen based on machining accuracy and electrode wear limits, while resistance seam welding grades depend on welding materials, current, and operating pressure.
3. Applications of CTIA's Tungsten Copper Electrode Wheel
(1) EDM of PCD Tool: Used to shaping, cutting edge processing, and resharpening of PCD tools, enabling complex tool profile machining.
(2) EDM of Cemented Carbide and Superhard Materials: Used for EDM of cemented carbide or other conductive superhard material workpieces depending on equipment and processing techniques, with applicability determined by workpiece materials, electrode structures, and equipment capabilities.
(3) Resistance Seam Welding: Wheel electrodes transfer welding current to workpieces during rolling, forming continuous or intermittent welds along metal sheet joints, suitable for tank seams, thin sheet lap joints, and automotive component welding.
(4) Welding of Metal Strips and Mesh: Used for resistance seam welding of copper strips, aluminum strips, stainless steel sheets, and metal mesh. Tungsten copper working surface offers good wear resistance and resistance to arc erosion. Material selection depends on workpiece material, welding current, and applied pressure.
4. Specifications of CTIA's Tungsten Copper Electrode Wheel
(1) Common Materials: CuW55, CuW75, CuW80, etc.
(2) Product Form: Disc, wheel, and customized shapes.
(3) Dimensions: Customizable according to application requirements.
(4) Customization: Requires specifying application (EDM or RSW), alongside equipment models, mounting hole dimensions, working face structures, and processing parameters.
