Aluminium metal matrix composites (AMMC) with SiC reinforcement is considered as a possible alternative to cast iron discs for cars mainly because of the significant reduction possible in the weight of the disc. However, it is costlier than cast iron, and is yet to be produced reliably in a large scale in mass production.

For motorcycles, stainless steel (SUS 410) is the most commonly used material. This material has reasonably good corrosion resistance, and can be induction hardened to increase the hardness for providing good wear resistance.
