FIELD: material processing.
SUBSTANCE: invention relates to the electroerosion processing of materials, mainly hard-to-process, including tungsten-free hard alloys and, above all, for stitching deep holes and small grooves in them. A material for the manufacture of an electrode-tool for electroerosion processing based on copper is proposed, containing, wt. %: boron nitride 2.90-3.10, aluminum 0.30-0.70, carbon 0.15-0.35, copper - the rest.
EFFECT: invention is aimed at increasing the electrical erosion resistance of electrode tools and increasing the productivity of the process of electroerosion processing.
