Which material are used to cam shaft?

Camshafts are typically made from materials that offer high strength and wear resistance, such as cast iron, forged steel, or aluminum alloys. Cast iron is commonly used for its good machinability and durability, while forged steel provides enhanced strength and fatigue resistance. In high-performance applications, aluminum alloy camshafts may be employed for their lightweight properties. Additionally, some camshafts may be surface-treated or coated to improve wear resistance.
