conventional automotive brake rotors are cast from G3000 grey cast iron. These work well with a pad material designed to operate using adherent friction. Most of the European system rotors are cast from a high carbon G4000 grey cast iron. These work well with a pad designed to operate using abrasive friction, such that the rotor is sacrificial just like the pad.
