Applications/Examples of results
Compared to materials like copper and copper-tungsten typically used for electrical discharge machining electrodes, carbide does not have good electrical conductivity. However, taking advantage of the extremely high hardness of carbide (around HRA90), we have developed a micro-diameter hole electrical discharge machining electrode made of carbide to meet the demand for drilling straighter and finer holes.
