Cast iron plays a crucial role in the automotive industry. Its good fluidity, reliable vibration damping, high wear resistance, and cost-effectiveness make it an indispensable material in the automotive sector. In particular, due to their good properties, gray cast iron and ductile cast iron are widely used in the manufacturing of key automotive components.
Gray cast iron, with its micro-structure containing flake graphite, effectively absorbs and reduces vibration and noise generated during engine operation. It is primarily used in the manufacturing of components such as engine blocks, cylinder heads, flywheels, torque converters, brake discs, and brake drums.
Ductile cast iron, achieved by adding magnesium to make the graphite spherical, enhances the strength, toughness, and ductility of the material. It is widely used for parts that require higher strength and toughness, including engine components (crankshafts, pistons, gears, etc.), suspension system parts (control arms, drive shafts, etc.), wheels, brake discs, and automotive gears.
