Abstract

Molded body is made from a material having a high graphite content with a thermoplast or duroplast as binder, and a pressed layer made from a material having a high metal content. The molded body is molded and sintered with a metallic body on/in the pressed layer. Preferred Features: The binder is present in an amount of 5-25 %. The material having a high metal content consists of copper and/or tin with additions of zinc, antimony, silver and bismuth, and stearates, fine graphites and graphite granules.
