GRAPHITE-COPPER COMPOSITE ELECTRODE MATERIAL AND ELECTRODE FOR ELECTRICAL DISCHARGE MACHINING USING SAID MATERIAL |
摘要 |
An object is to provide a graphite-copper composite electrode material that is capable of reducing electrode wear to a practically usable level and to provide an electrical discharge machining electrode using the material. A graphite-copper composite electrode material includes a substrate comprising a graphite material and having pores, and copper impregnated in the pores of the substrate, the electrode material having an electrical resistivity of 2.5 µ©m or less, preferably 1.5 µ©m or less, more preferably 1.0 µ©m or less. It is desirable that the substrate comprising the graphite material have an anisotropy ratio of 1.2 or less. It is desirable that an impregnation rate Õ of the copper in the electrode material is 13% or greater. It is desirable that the substrate comprising the graphite material have a bulk density of from 1.40 Mg/m 3 to 1.85 Mg/m 3 . |
