Abstract

1. A two-component carbon brush including a layer which is free of metal or has a low metal content and a layer which has a high metal content, characterised in that one of the two layers (2, 3) is divided into individual sections by one or more slots (4), and both layers are formed of dense materials having different coefficients of thermal expansion.
