Our company supplies natural flake graphite specifically for semi-metallic friction materials. Since the 1970s, semi-metallic friction materials have been widely used in clutches and automatic transmission linings. These materials are made by binding graphite with metal powders, steel fibers, and clay powders using synthetic resins. They are primarily used in high-speed equipment, such as aircraft, trucks, and off-road vehicles, for braking systems and clutch plates.

In recent years, asbestos has gradually been replaced by graphite. In some semi-metallic linings, the graphite content has increased from 1-2% to around 10%. The consumption of graphite in this field depends on the development of the automotive industry.
