1. Cast iron: A common material for brake discs, widely used due to its low cost, significant weight, and good high-temperature resistance.
2. Ceramic: Ceramic brake discs offer excellent wear resistance, lighter weight, and superior thermal conductivity, though they come at a relatively high cost.
3. Carbon fiber composite: Brake discs made from this material are lightweight, highly thermally conductive, and strong, but they are extremely expensive to manufacture.
