Magnetic track brake
- comprising at least one of a magnetic base and a carrier member and
- a pole shoe area comprising a magnetic flux-carrying area and a magnetic flux-separating area,
- wherein at least one of the magnetic flux-carrying area and the magnetic flux-separating area comprises, at least in part, in the form of a friction material a sintered material, wherein the magnetic flux separating area is an intermediate strip extending in a longitudinal direction of the magnetic track brake, wherein the sintered material comprises the following composition:
- 80% to 90% magnetically conductive and/or magnetically non-conductive material 0.5% to 5% molybdenum sulfite 0.5% to 5% carbon 0.5% to 2% silicon carbide.
