Abstract
A sintered friction material comprises a metallic matrix and granular constituents embedded in the matrix. The metallic matrix comprises a copper base alloy. The friction material is characterized in that the granular constituents comprise at least one sintered cemented carbide in a proportion of up to 9 weight percent, based on the total weight of the friction material. Furthermore, a friction body, in particular for clutches and brakes, that comprises a friction lining with at least one layer made of the sintered friction material, and a method for the production of a friction lining with the sintered friction material are described.
