Silicon for Ceramic Brake Discs

Elkem offers silicon for use in production of ceramic brake discs, both within the automotive and the aircraft industries. 

Ceramic matrix composites (CMC’s) such as carbon fibre-reinforced silicon carbide (C-SiC) offer superior properties at high temperatures vs. traditional iron discs. Our silicon is used in the liquid silicon infiltration (LSI) step during production of ceramic brake discs.
