EDM-C3

POCO's EDM-C3 is a high quality graphite infiltrated with copper, recommended where speed, wear, and surface finish are important. Unequalled for fragile electrodes, many EDM'ers choose this grade to compensate for operator inexperience or where poor flushing conditions exists.

 

Applications

Fine detailed electrodes where strength is critical
Threading electrodes
Aerospace applications
Plastic injection molds
Machining of carbide
Small hole drilling
