Copper-Tungsten (CuW) Alloy with Shank — Edgetech

Edgetech’s CuW alloy electrodes with shank (CuW bi-metal) are fabricated using advanced vacuum welding technology to bond copper-tungsten composite material securely onto a strong iron backing (shank). This bonding method delivers exceptional mechanical integrity and allows for enhanced EDM (Electrical Discharge Machining) performance.

Key Features & Advantages

  • Superior Bond Strength – Vacuum welding forms a robust metallurgical bond between the CuW alloy and iron shank, ensuring durability during high-precision machining.
  • Optimized for EDM – The iron-backed design not only offers mounting convenience but also guarantees stability and precision in die-sinking EDM applications.
  • Magnetic Shank for Easy Handling – The ferromagnetic iron shank enables quick attachment to CNC fixtures, streamlining setup and enabling detailed machining of the CuW surface.
  • Flexible Design Configurations – Customers can opt for one of two bonding configurations:
    1. Flat-side bond — where the shank adheres along a flat surface of the CuW block.
    2. Top-side bond — where the shank is bonded on the upper side, offering alternate geometry and machining advantages.
