What material used in connecting rod?

Connecting rods are typically made from high-strength materials such as forged steel, aluminum alloys, or cast iron. Forged steel is the most common choice due to its Excellent strength-to-weight ratio and durability, making it suitable for high-performance applications. Aluminum alloys are used in lighter applications to reduce weight, while cast iron is sometimes employed for cost-effective solutions in lower-performance engines. The choice of material depends on factors such as engine design, performance requirements, and manufacturing considerations.
