Brake pads
Alumina is used in brake pads to clean contamination from the disc or drum coming from wear of other brake pad ingredients, especially carbon-based raw materials. Almatis premium aluminas are typically used as 2-10% of the pad formulation, depending upon whether it is a drum or a disc brake system.
