Abstract

A process for making brushes, suitable for use for current collector rings in electrical machines, comprises mixing natural graphite with pitch and compacting and baking this mixture at approximately 800 DEG C., followed by further heat treatment in a non-oxidizing atmosphere in a temperature range of 2300 DEG to 2700 DEG C. for at least 30 minutes. The non-oxidizing atmosphere, e.g. carbon monoxide, may be obtained by carrying out the further heat treatment in a graphite container.
