SPARKAL® erosion electrodes

The high quality of our SPARKAL® electrodes is assured by specializing in tungsten-heavy metal alloys. They exhibit low wear, optimum contour sharpness, are easy to work with and achieve a high level of efficiency

The key step in the manufacture of SPARKAL® erosion electrodes is infiltration. After the porous tungsten blank has been compacted, it is infiltrated with copper, sintered and then machined to produce the geometry required by the customer. SPARKAL® erosion electrodes produced using our WCu composite material provide high wear resistance combined with excellent electrical conductivity
