Application Scenario
Material Introduction
Brake drums are commonly made from high-grade gray or ductile cast iron, chosen for its excellent heat dissipation, dimensional stability, and resistance to thermal fatigue during repeated braking. Carefully controlled alloy composition and heat treatment improve surface hardness and wear resistance, while precision machining and dynamic balancing ensure consistent contact with brake shoes and reduced vibration. Protective coatings or phosphate finishes are often applied to guard against corrosion and extend service life in demanding environments.
