PURPOSE:To sufficiently lower electric resistance and to improve a sliding property, strength, wear resistance, and impact resistance by sintering the kneaded mixture composed of carbon aggregate, metal powder and metal fibers. CONSTITUTION:The carbon aggregate (e.g.: coal coke) of 10 to 25wt.% volatile content, 25 to 70wt.% metal fibers (e.g.: copper fibers), the metal powder (e.g.: copper powder) of 0.1 to 20wt.% by the weight of the metal fibers, and a binder (e.g.: coal tar) are kneaded and after the kneaded mixture is molded, the molding is sintered in a nitrogen atmosphere. |
