Over the year’s rocker arms have been optimized for better performance, durability, toughness and high dimensional stability, wear resistance, strength, etc. in terms of on design and material. Economic factors are also the reason for optimization of rocker arms. The evaluation of material properties for different grades of rocker arms is consider for analysis to choose and recommend a best one for a specific application, as rocker arms are performing an important role during the operation of engines by controlling the inlet and exhaust valves to open and close at correct timings. Various types of rocker arms are used in vehicles also different materials are used or making rocker arms. This project work describes four essential properties, chemical composition, tensile strength, microstructure and hardness of three important types of materials used for making rocker arms, namely aluminum alloy, grey iron and spheroidal graphite iron. Identification of superior grade for making rocker arms, to enhance cyclic load, based on evaluation of different grade material properties is the expected outcome of this project. The experimental results obtained, for the above material properties, are presented in this report. The effect of induction hardening on the tip of the rocker arm, for the spheroidal graphite iron is also reported.
